By using multiple pulleys in a system known as a block and tackle, the force required to lift a weight can be significantly decreased, although this requires moving the force over a greater distance.

Perhaps the humble block and tackle — multiple parallel pulleys to reduce the effort of lifting — is not such a common sight as it once was in this age of hydraulic loaders, but it rema… ...

The ParaPull is an ingenious block and tackle pulley system scaled down to work with common 550 paracord. It fits in your pocket and gives you a 6:1 mechanical advantage over any heavy object.

A pulley system with two pulleys is used to lift a 240 N load. The effort required to lift the load is 120 N. Calculate the mechanical advantage of the pulley system.
