WebThe mechanical advantage (MA) of a machine is the factor by which it multiplies any applied force. The MA may be calculated from the ratio of the forces involved or from the ratio of the distances through which they move. WebMechanical advantage is equal to the velocity ratio. An ideal machine is free from any friction and its efficiency is 100% or 1. The efficiency of a machine is defined as the ratio of mechanical advantage and velocity ratio i.e., Efficiency (η) = Mechanical advantage (MA) Velocity ratio (VR) Since in an ideal machine, efficiency = 1.
