MA of Pulley

A system of pulleys allows a mechanic to lift an 1800 N engine. a. If the mechanic exerts a force of 600 N on the pulley system, what is the Of (output force) in this problem?

• 1800 N

• 600 N

• unknown

A system of pulleys allows a mechanic to lift an 1800 N engine. a. If the mechanic exerts a force of 600 N on the pulley system, what is the correct equation to be used to get the MA of this pulley?

• MA= IF/OF

• MA= OF/IF

• MA= OF x IF

• MA= OF- IF

• input force

• mechanical advantage of the pulley

• output force

• movable pulley

Using the illustration, how are you going to calculate the MA of pulley without using an equation?

• The mechanical advantage (MA) of a pulley system is equal to the number of ropes supporting the effort force..

• The mechanical advantage (MA) of a pulley system is equal to the number of ropes supporting the fixed pulley.

• The mechanical advantage (MA) of a pulley system is equal to the number of ropes supporting the movable load.

• Cannot be determined
