To calculate the effort put into the machine, we can use the formula:
Effort (E) = (Load / Velocity Ratio) / Efficiency
Given:
Load = 1000N
Velocity Ratio = 4
Efficiency = 75%
Substituting the values into the formula:
Effort (E) = (1000N / 4) / 0.75
Effort (E) = 250 / 0.75
Effort (E) ≈ 333.33 N
Therefore, the effort put into the machine is approximately 333.33 Newtons (N).
