The hydraulic jack in Figure 1 is operated by a hand lever. A force of 200 N is applied at the end of the lever; the plunger is pinned to the lever at the distance shown from the fulcrum. Neglecting friction, leakage and the small difference in level between the plunger and the ram, determine (a) the pressure in the oil (in MPa), (b) the load W that the ram can lift (in kN), and (c) the distance the ram rises for one full plunger stroke of 30 mm (in mm).
