An effort of 4 k g f is applied on a machine through a displacement of 100 cm when a load of 100 kg through a distance of 4 cm. find the velocity ratio mechanical advantage and efficiency of the machine.

Effort= 4 kgf
Effort Arm=100 cm
Load=100 kgf
Load Arm=4cm

Velocity Ratio=Effort Arm/Load Arm
= 100/4
= 25

Mechanical Advantage=Load/Effort
= (100/4)kgf
= 25 kgf

Therefore, Velocity Ratio=25; Mechanical Advantage=25 kgf
