Question

The inclined plane with base angle 30` is used to lift a load of 500N using 400N effort.The efficiency of the plane is

Answer 1

Explanation:

efficiency = (work output / work input) x 100%

efficiency = ([load force x load distance] x [effort force x effort distance]) x 100%

efficiency = (500 N x 1.0 m) / (100 N x 10 m) x 100%

efficiency = (500 N x m / 1000 N x m) x 100%

efficiency = 0.5 N x 100%

efficiency = 50%
