Question 1 Report

A plane inclined at an angle of 30o to the horizontal has an efficiency of 60%. The force parallel to the plane required to push a load of 120N uniformly up the plane is

60N

100N

120N

200N

240N

Answer Details

V.R = $\frac{1}{s i n 30}$ = 2

Efficiency = $\frac{m . A}{V . R}$ x 100%

60 = $\frac{120}{e f f o r t}$ x $\frac{1}{2}$ x 100

Effort = 100N
