Question

A system of police allows a mechanic to lift in 1800 Newton engine after improving the design of the police system and mechanic engine with a MA how much is required to lift the engine

Answer 1

If the mechanic improved the design of the pulley system, resulting in a Mechanical Advantage (MA) of 2, then the force required to lift the 1800 Newton engine would be 900 Newtons.

Force required = Weight of the object / Mechanical Advantage
Force required = 1800 N / 2
Force required = 900 N

Therefore, the mechanic would need to apply a force of 900 Newtons to lift the engine with the improved pulley system.
