Question
If an effort of 60 Newton is needed to lift a load of 150 with is a three pulley system. what is the efficiency of this machine?
Answers
GPT 3.5
To determine the efficiency of the machine, we first need to calculate the work input and work output.
Work Input = Force * Distance
Work Input = 60 N * d
Work Output = Load * Distance
Work Output = 150 N * d
Efficiency = (Work Output / Work Input) * 100%
Efficiency = (150d / 60d) * 100%
Efficiency = 2.5 * 100%
Efficiency = 250%
Therefore, the efficiency of this machine is 250%. This means that the machine is able to lift the load with 250% efficiency, which is very high.
