Answer:
The efficiency of the machine is 85.5%
Explanation:
Mechanical advantage = Load/Effort
= 600/350 = 1.71
Velocity ratio = distance moved by effort/distance moved by load
= 60/30 = 2
Efficiency = (M.A/V.R) × 100%
= (1.71/2) × 100
= 0.855 × 100
= 85.5%
The efficiency of the machine is 85.5%
Given:
Load= 600N
Effort= 350N
distance between the fulcrum and the effort = 60cm
distance between the load and the fulcrum = 30cm
The formula of the mechanical advantage(MA) of a lever is given as
Mechanical advantage = Load/Effort
Mechanical advantage = [tex]\frac{600}{350} =1.71[/tex]
Velocity ratio = distance moved by effort/distance moved by load
Velocity ratio = [tex]\frac{60}{30} =2[/tex]
Efficiency = (M.A/V.R) × 100%
= (1.71/2) × 100
= 0.855 × 100
Efficiency= 85.5%
