The document describes seven experiments involving the control of a double-acting cylinder using solenoid valves and relays. Experiment 5 involves directly controlling the cylinder using a solenoid valve. Experiment 6 introduces indirect control using a relay and solenoid valve. Experiment 7 presents two methods of indirect control using a relay, solenoid valve, and switches - with either AND or OR logic. The experiments aim to demonstrate different wiring configurations for operating a double-acting cylinder.
