What is called efficiency? Under what conditions will the efficiency of a real gate be close to unity?
| October 24, 2020 | Education
The ratio of useful work to work expended is called the efficiency of the mechanism:
Efficiency = A (n) / A (h)
The efficiency of the gate is close to unity if the mass of the gate and the rope is much less than the mass of the load being lifted and if the work force of the fenian is less than the work of gravity.
