This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - How to calculate the output force of a hydraulic cylinder using Pascal's Law (F=PA) and account for the rod area during retraction. - The distinct roles of solenoids (mechanical actuators) and relays (electrical switches) in a control system. - How to interpret the symbols for Directional Control Valves (DCVs), specifically the meaning of ports and positions (e.g., a 4/3 valve). - The function of a hydraulic accumulator and how to apply Boyle's Law for exam-style calculations, remembering to use absolute pressure. - A memorable mnemonic (E-M-F-M: Electrical, Magnetic, Fluid, Mechanical) to trace energy and control signals through a complete electromechanical and fluid power system.
