Which machine has the greatest mechanical efficiency a block and tackle or a lever?
January 29, 2009 12:02PM
In theory there is no difference in efficiency (it would be 1), but in practice I think a block and tackle would lose more force to friction in the pulleys and between the rope and pulleys.

What is the function of a block and tackle?
A block and tackle consists of a system of pulleys with a rope and hook. It is a simple machine which lets you lift a heavy weight more easily. We say it gives you a mechanical advantage,or that it is a force multiplier because it lets you trade a large distance by which you pull the rope using a small effort for a small distance lifting the heavy weight. An example is an engine hoist.

How is a block and tackle is used today?
The block and tackle is still used in the manner it has always been used, to gain a mechanical advantage in lifting or pulling objects. It is used extensively aboard ships today. I used them in the Navy. I have also used the block and tackle on construction jobs when rigging heavy loads to move them. The block and tackle is very handy when there is no source of electric power available and in remote locations.
