Answer: 260N
Explanation:
This question will be solved based on the assumption that efficiency is 100% ie 1
Efficiency = work done by the machine(work output)/work done on the machine (work input)
Since Workdone = Force × Distance
Work output = Load × distance moved by load = 0.2×Load
Work input = Effort×distance moved by effort = 30×1.4 = 52 Joules
Substituting this value info the efficiency formula we have
1 = 0.2Load/52
52 = 0.2 × Load
Load = 52/0.2
Load = 260N
Therefore, the weight of the load is 260N
