Physics often focuses on simplifying complex phenomena to better understand and predict the natural world. This art of idealization is a cornerstone of mechanics, where we frequently encounter the concept of a “particle” or “point mass.” Within this context, the moment of inertia plays a crucial role, particularly in rotational dynamics. In thermodynamic equilibrium, all…
A planetary gear system also known as an Epicyclic gearing or planetary gearing. It consists of spur gears arranged in an epicyclic configuration. In this setup, a central gear, known as the sun gear, acts as the input and drives the system. Multiple “driven” gears, or planets, orbiting the sun gear within a gearbox. These planets mesh…
What’s the difference between energy vs power? In the realm of physics and engineering, the concepts of energy and power are fundamental but often misunderstood. While they are closely related, they represent distinct aspects of physical systems. Energy is the ability to do work, while power is the rate at which work is done or…
Have you ever wondered how an automotive suspension system is designed? From ATVs (all-terrain vehicles) to locomotives to modern passenger automobiles most types of vehicles that move people from one place to another rely on a suspension system to improve ride quality and comfort. There are a few common types of automotive suspension systems such…

The 800-lb load is being hoisted at a constant speed using the motor M, which has a weight of 90 lb. Determine the resultant internal loadings acting on the cross section through point B in the beam. The beam has a weight of 40 lb/ft and is fixed to the wall at A. Sample problems…
The sky hook is used to support the cable of a scaffold over the side of a building. If it consists of a smooth rod that contacts the parapet of a wall at points A,B, and C, determine the normal force, shear force, and moment on the cross section at points D and E. Support…
The force acts on the gear tooth. Determine the resultant internal loadings on the root of thetooth, i.e., at the centroid point A of section a–a.
