A double acting cylinder (without a spring return) has a diameter of 2 inches, a length of 12 inches and its' piston rod has a diameter of 0.4 inches. It is being used in an application in which the piston rod is attached to a linkage (only a guided sliding block and one bar of the linkage is shown) which requires a 300 lb. force pushing on the linkage during extension of the piston rod and a 290 lb. force pulling on the linkage during retraction of the piston rod. a. Assuming the input pressure to the cylinder is the same during extension and retraction find the minimum amount of pressure needed. Do not include frictional resistance in the cylinder in your calculation. b. Determine the maximum allowable stroke of the piston rod (made of steel) for the following two mounting configurations: flange mounted at the piston end and flange mounted at the rod end. Use a factor of safety equal to one. A double acting cylinder (without a spring return) has a diameter of 2 inches, a length of 12 inches and its' piston rod has a diameter of 0.4 inches.
