Ablock and tackle is used to raise a 72.0 n crate 12.3 m from the loading dock to the ship. this requires a force of 25.0 n to be applied by the longshoreman. (a) what is the mechanical advantage of the block and tackle? (b) how much rope must be pulled? note: assume that ima = ma. (c) the longshoremen have only a 40 m rope that they are told not to cut. they use this for the block and tackle. how does this affect the efficiency of the block and tackle

Hurry up ! simple machines make work easier. most simple machines reduce the amount of effort force needed to move an object. this cart has a set of wheels. the wheels are actually simple machines: the wheel and axle. how can we change these wheels to decrease the amount of effort force needed to move the wagon? a) use a larger wheel and axle. b) make the radius of the axle larger in diameter. c) make the radius of the wheel larger in diameter. d) make the radius of the wheel smaller in diameter. we can classify both the shovel and the garden trowel as compound machines. this is because each garden tool contains two simple machines, a) a lever and a wedge. b) a blade and a handle. c) a lever and a pulley. d) an inclined plane and a wedge. a block-and-tackle is a machine that uses pulleys to lift heavy items. a person pulls on one end of a rope with an effort force. the other end is attached to the item, or load. the table shows the results of testing several block-and-tackle designs to pull the load one meter off the ground. which design has the greatest efficiency? a) block-and-tackle a b) block-and-tackle b c) block-and-tackle c d) block-and-tackle d
