Question 2 (Hydraulic systems) A piston can move either from left to right or from right to left in a double-acting cylinder with two ports. In figure 2a) the piston moves from left to right, and in figure 2b) it moves from right to left. The internal diameter of the cylinder is 50 mm and the diameter of the piston rod is 20 mm. Assume there is no friction between the piston and inner walls of the cylinder or elsewhere in the system. Calculate the maximum force that can be applied by the piston in both case a) and case b) if the pump provides a pressure of 150 kPa in both cases. PUME Pump Figure 2 (a) (b)

Why does metal feel colder than wood, if they are both at the same temperature? O Metal is a conductor, wood is an insulator. Metal conducts the heat away from your hands. O Wood does not conduct the heat away from your hands as well as the metal, so the wood feels warmer than the metal. O All of the above
