Question

3. What is mechanical advantages and velocity ratio of a machine?

Answer 1

Mechanical advantage is the ratio of load to effort of machine or we can say it is the ratio of output of machine to the input of the machine. Velocity ratio is also defined as velocity of

Answer 2

Mechanical advantage:

i. The ratio of load to effort on a balanced lever is called mechanical advantage.(Definition)

ii. Mechanical advatage (MA) = Load (L)/Effort (E) (Formula)

Velocity ratio:

i. The ratio of effort distance to load distance is called velocity ratio.(Definition)

ii. Velocity ratio (VR) = effort distance(Ed)/ load distance(Ld). (Formula)
