A machine has an efficiency of 60%. If the machine is required to overcome a load of 30N with a force of 20N. Calculate its mechanical advantage.
- A1.5
- B0.9
- C0.7
- D2.5
Explanation
Mechanical Advantage (M.A.) is defined as the ratio of Load to Effort (Load / Effort). Here, Load = 30N and Effort = 20N, so M.A. = 30 / 20 = 1.5.
