Question

Differentiate between velocity ratio efficiency and mechanical advantage.

Answer 1

Answer:

Mechanical advantage is defined as the ratio of resistance overcomes to the effort applied. Velocity ratio of simple machine is the ratio of distance travelled by the effort to the distance travelled by load in a machine. The efficiency of a simple machine is defined as the ratio of useful work done by machine (output work) to the total work put into the machine (input work). This note provides us with an information about mechanical advantage, velocity ratio and efficiency.
