WebFor a machine of a given design, due to friction and weight of the moving parts of machine, the velocity ratio does not change, but both mechanical advantage and the efficiency decreases. Velocity Ratio : V. R = V L V E WebIt is a unitless expression since the two ratio quantities are the force. Mechanical advantage is also defined as the force created by the machine to the for applied on it. The formula of mechanical advantage is given as: M A = F B F A. Wherein, MA is the mechanical advantage, FB = force of the object and. FA = effort to overcome the force of ...
