Block and tackle - Block and tackle A block and tackle is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift or pull heavy loads. The most common arrangement is to have a set of fixed pulleys all mounted on a single axle, and another set left to move. Each set is called a "block" (the rope is the "tackle"). The mechanical advantage of a block and tackle is equal to the number of lines running between the two blocks. For example, a block and tackle consisting of three fixed and three moving pulleys has six lines going between the pulleys, which gives it a mechanical advantage of 6. This enables the lifting of weights six times heavier than would.
Versatackle knot - Versatackle knot A versatackle is a way of simulating a block and tackle without actual pulleys or deadeyes. It consists of two loops with the rope passed back and forth between them. http://www.geocities.com/roo_two/Versatackle.html.
Horatio Nelson Jackson - which he named "Vermont", after his home state, bid his wife goodbye (she took the train to Vermont to meet him when he arrived), and left San Francisco on May 23, carrying coats, suits, canvas protective suits, sleeping bags, blankets, canteens, a water bag, an axe, a shovel, a telescope, tools, spare parts, a block and tackle and cans for extra gasoline and oil, a camera, a rifle, ashotgun and pistols. Heeding the failed attempt by automobile pioneer Alexander Winton (founder of the Winton Motor Carriage Company) to cross the Southwestern desert, Jackson decided to take a more northerly route. A route through the Sacramento Valley and along the Oregon Trail also allowed them to avoid the higher passes in the Rocky Mountains. The car was transported by ferry from San.
Glossary of American football - center - a player postition on offense coffin corner - the corner of the field of play. A punter, if he is close enough, will often attempt to kick the ball out of bounds close to the receiving team's goal line and pin them back near their own end zone. cornerback - a player position on defense crackback block - an illegal block delivered from the back by an offensive player who had left the area of close line play and then returned to it. defensive back - a cornerback or safety on the defensive team; commonly defends against wide recievers on passing plays. Generally there are 4 defensive backs playing at a time. defensive end - a player position on defense defensive tackle - a player position on defense defensive.
Fleeming Jenkin - Spartivento, in the south of Sardinia, and a point near Bona, on the coast of Algeria. It was a gutta-percha cable of six wires or conductors, and manufactured by Glass & Elliott--a firm which afterwards combined with the Gutta-Percha Company, and became the Telegraph Construction and Maintenance Company. Brett laid the cable from the Result, a sailing ship in tow, instead of a more manageable steamer; and, meeting with 600 fathoms of water when twenty- five miles from land, the cable ran out so fast that a tangled skein came up out of the hold, and the line had to be severed. Having only 150 miles on board to span the whole distance of 140 miles, he grappled the lost cable near the shore, raised it, and 'under-run' or passed it.
American football - team sport that rewards players' speed, agility, tactics, and brute strength as they push, block, tackle, chase, and outrun each other, trying to force a ball further into enemy territory for one hour of game time, which translates into three to four hours of real time. American football is often seen as a metaphor for war, with a great deal of personal violence occurring on every play as players often weighing 300 pounds or more shove each other with every ounce of their strength, and with a clearly defined front line, moving up and down the field, separating the offensive and defensive squads. American football does not much resemble soccer, the sport which most of the rest of the world, except Canada, calls "football". It is a descendant of Rugby Union,.
Sheepshank - (in decreasing order of usefulness): secure a load in a way that can be easily undone when no longer needed, but provides a block and tackle mechanism allowing a load to be secured much more tightly than is otherwise possible. shorten a rope (though there are better ways to do this) bypass a section of frayed rope - useful in poor economies where rope is expensive Comments: Structure: Tying: The knot is constructed as follows: pull a section of rope back and lay it alongside the rope, so that the rope forms a Z approximately 20 cm long. flatten the Z so that there are 3 sections of rope lying alongside each other, with two U-bends where the rope reverses direction. at each U-bend, grasp the U-bend in one hand, thus.
Rigging - projects beyond the jib-boom, answers to a topgallant mast. The whole body of ropes by which the yards, booms and sails are manipulated constitute the “running rigging,” since they are “in constant use, to trim yards, and make or shorten sail” (Admiral Smyth, op. cit.). The rigging must also provide the crew with the means of going aloft, and with standing ground to do their work when aloft. Therefore the shrouds (see below) are utilized to form ladders of rope, of which the steps are called ratlines, by which the crew can mount. Near the heads of the lower masts are the tops—platforms on which men can stand—and in the same place on the topmasts are the “crosstrees,” of which the main function is to extend the topgallant shrouds. The yards.
Paul Hornung - from a losing team (his University of Notre Dame team finished 2-8 that year) ever to win the trophy. Highly versatile, Paul Hornung was a quarterback who could run, pass, block and tackle and is the person most football observers consider as the greatest all-around football player in the University of Notre Dame’s history. In the 1956 season, he led his team offensively in passing, rushing, scoring, kickoff and punt returns and punting. He also played defense and led his team in passes broken up and was a team second in interceptions and tackles made. In 1957, after graduating university with a degree in business, Hornung was drafted number one overall into the National Football League by the Green Bay Packers with whom he would go on to win four league.
Pulley - the total force on the axle balances the total force provided by the tension in the rope (which is constant in magnitude in each segment). A movable pulley has a mechanical advantage of 2. So, for instance, if one end of the rope is attached to a fixed object, pulling on the other end will apply a doubled force to any object attached to the axle. This can be increased by using a block and tackle, where there are several pulleys on each axle. Pulleys are usually counted as one of the simple machines. Plutarch reported that Archimedes moved an entire warship, laden with men, using compound pulleys and his own strength. Pulley Images Early Pulleys Single Fixed Pulley Single Movable Pulley.
Offensive team - center, and then either handing off to a back, passing to a reciever or a back, or running the ball himself. The offensive unit in American football consists of a quarterback, linemen, backs, and recievers. The function of the linemen is to block. The line consists of a center, two guards, two tackles and one or two tight ends. Backs include halfbacks and a fullback, who usually block, run the ball, or receive a pass. The function of the wide receivers is to catch passes. center - the center performs the normal blocking functions of all linemen and, in addition, is the player who puts the ball in play by means of the snap. guard - the two guards are the offensive linemen directly on either side of the center and.
National University of Lesotho - that matter, any other overseas University. As early as 1952, attempts by the college to secure a special relationship with the University of London, through the Inter-University Council for Higher Education Overseas (Commonly referred to as the I-VC) had been 'unsuccessful. In view of the prevailing difficulties, seen as a danger to the development of university education in Basutoland in 1962, the General of the Oblate Congregation requested Fathers Banim, 0. M.I. and A. W. Hall, O.M.I. to visit Roma and assist the College in finding a practical solution to its problems. The South African Government had declared its intention not to admit African students from outside South Africa into the University College of Fort Hare, and the Natal Medical School (Wentworth) after December 31 1953. Although this ban was relaxed.
Mechanical advantage - Pulleys are wheels that are connected together with ropes. In doing so the direction of the force on the rope can be changed, with little loss in force due to friction (for the same reasons as the wheel). However pulleys can be "added together" to create additional mechanical advantage by having the rope looped over several pulleys in turn. A pulley with one rope (single fixed pulley) has an MA = 1, that is, no advantage (or disadvantage). A pulley with two ropes (single moveable pulley) has a MA = 2. A pulley with 6 ropes (block and tackle) has a MA = 6. Inclined Plane: MA = length of slope ÷ height of slope Most generally, the mechanical advantage is calculated thus: MA = (the distance over which force is.

This unit is responsible for getting the ball into play on the right call, plus blocking his assigned man. If anyone on the field moves past the line of scrimmage before the center hikes the ball, they will be called on the foul. But if any offensive lineman flinches, they will be called on the offsides. Guards A guard is the man who is set next to the center. The guard’s job is mainly speed blocking and pulling. When a guard pulls, he traps the man down on the.

Kartchner Caverns State Park - of the town of Benson. The park encompasses most of a down-dropped block of Palaeozoic rocks on the east flank of the Whetstone Mountains in the Coronado National Forest. it is carved out of limestone and filled with spectacular speleothems which have been growing for 50,000 years, and are still growing due to careful development and maintenance. The caverns were apparently unknown to man until 1974, when two amateur cavers found a narrow crack in the bottom of a sinkhole, and followed the source of moist air towards what ended up to being over 2½ miles of pristine cave passages. In the desire to avoid vandalism, the discoverers keep the location of the passages a secret for years; their story is finally made public in 1988 when the landowners sell the.
