1.
Two double acting pneumatic cylinders (A, B) in a process industry should extend
together at the same time to open two different valves. On the return stroke both
cylinder rods return at the same time. The starting is by a detent switch. Both the
cylinders are of the same size with the same stroke length. In terms of notation, the
cycle is required to go on till the detent start-up switch is pressed again. Draw the
