MET230L: Hydraulics and Pneumatics Lab Mid-Term Assignment Answers

This document contains the complete solution to a MET230L Hydraulics and Pneumatics Lab Mid-Term assignment. The assignment covers five exercises involving pneumatic circuits. Exercise 1 focuses on identifying components, building a circuit in simulation software, and analyzing cylinder behavior with flow control and quick exhaust valves. Exercise 2 modifies the circuit to achieve a faster return stroke. Exercise 3 involves building a circuit with a shuttle valve to control cylinder extension and retraction. Exercise 4 explores a circuit with a pneumatic proximity switch and continuous cylinder cycling. Exercise 5 requires modifying the circuit from Exercise 4 to initiate operation only when the cylinder is fully retracted and to complete a single forward and backward cycle upon pressing a push button. The solutions include circuit diagrams, explanations, and simulation results.
