Question 1 Report

A 20kg mass is to be pulled up a slope inclined at 30o to the horizontal. If the efficiency of the plane is 75%, the force required to pull the load up the plane is [g = 10ms-2]

13.3N

73.5N

133.3N

53.2N

Answer Details

Efficiency = m.A x $\frac{1}{V . R}$ X 100%

75 = $\frac{20 \times 10}{e f f o r t}$ x $\frac{1}{\frac{g}{s i n θ}}$ x 100%

Effort = 133.3N
