Mechanical Advantage:
- In a simple machine when the effort(P) balances a load (W), the ratio of the load to the effort is called MA.
Velocity Ratio:
- It is the ratio between the distance moved by the effort to the distance moved by the load.
Efficiency:
- It is the ratio of output to input. In a simple mechanism, it is also defined as the ratio of mechanical advantage to the velocity ratio.
- In actual machines, a mechanical advantage is less than the velocity ratio
- In an ideal machine, the mechanical advantage is equal to the velocity ratio.
Calculation:
Given:
Effort (P) = 15 units, MA = 3
Load, W = 45 units
