(b) Find the mechanical advantage in an ideal case.

(a) The weight W of the scale is greater than E. The effort arm is 30 cm and the load arm is 10 cm. In order to balance the scale weight (W) of scale has to be more than effort (E). (b) Given, Load arm = 10 cm Effort arm = 30 cm As we know that, Substituting the values in the formula we get,
