Answer:
"where crests and troughs have their maxima at the same time"
Crests and troughs are 180 deg out of phase and when they have their maxima at the same time and place, their net contribution will be zero"
Efficiency = Mechanical advantage / Velocity Ratio:
0.60 = M.A./6
MA = 0.6 * 6 = 3.6
The mechanical advantage is 3.6
Mechanical advantage = Force out / Force in
3.6 = 3000/ Force in
Force in = 3000/3.6
Force in = 833.33 N
Answer: 833.33N
