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… ...

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.
