FE Mechanical Exam Prep 86, Bearings Gears and Power Transmission

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 gear ratios and their inverse effect on speed and torque. - That an idler gear's only function is to change rotational direction, not the overall system gear ratio. - How to find the total efficiency of a power transmission system by multiplying individual component efficiencies. - The L10 bearing life formula and the critical exponent difference between ball bearings (p=3) and roller bearings (p=10/3). - The necessity of converting rotational speed from RPM to radians per second for power and torque calculations (P = Tω).
