MET230L Hydraulics and Pneumatics Lab Final Exam Exercises Solutions

This document presents the solutions to a practical final exam for a Hydraulics and Pneumatics Lab course (MET230L). The exam consists of four exercises involving the design and simulation of pneumatic circuits. Exercise 1 focuses on modifying a circuit to control cylinder retraction using either full extension or an additional valve. Exercise 2 explores the control of cylinder extension and retraction using different valve combinations. Exercise 3 examines cylinder control with sensor and push-button combinations. Finally, Exercise 4 involves the design of an electro-pneumatic circuit with two cylinders operating in a repeating sequence. Each exercise includes circuit diagrams and answers to specific questions about the circuit behavior, all completed using simulation software. The solutions demonstrate a thorough understanding of pneumatic components and circuit design principles.
