The input force of a pulley system must move 8.0 m to lift a 3000-N engine a distance of 2.0 m. What is the IMA of the system?

The ideal mechanical advantage (IMA) of the pulley system is calculated by the formula IMA = distance output / distance input. In this case, the distance output is 2.0 m (the distance the engine is lifted), and the distance input is 8.0 m (the distance the force must move). Therefore, the IMA of the system is 2.0 / 8.0 = 0.25.
