Hook, Line and Stinker dynamite are rolling back to him and the detonator. Thus, one push of the plunger blows him up. 6. Using a rope and a pulley, the Coyote raises a baby grand piano high above the road. As the Road Runner passes, the Coyote lets go of the rope, which sticks in the pulley. The Coyote jumps on top of the piano, which loosens the rope and causes the piano - and the Coyote - to drop to the ground. Dazed, the Coyote opens his mouth to reveal that the piano keys are now his teeth; he plays "Taps" on them
Block and tackle more precise estimate of efficiency is possible by use of the sheave friction factor, formula_12 (which may be obtainable from the manufacturer or published tables). The relevant equation is: Typical formula_12 values are 1.04 for roller bearing sheaves and 1.09 for plain bearing sheaves (with wire rope). The increased force produced by a tackle is offset by both the increased length of rope needed and the friction in the system. In order to raise a block and tackle with a mechanical advantage of 6 a distance of 1 metre, it is necessary to pull 6 metres of rope through the
