A hydraulic ram presses a steel support into the ground. Before the ram is modified, the support moves 0.25 m in the direction of the force during each operation. After the modification, the force is 20% greater. The work done during each operation must be 8% greater than before.
Calculate the distance moved by the support during each operation after the modification.
