Understanding Moment of Inertia
Physics often focuses on simplifying complex phenomena to understand better 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…

Planetary Gear: Explained
A planetary gear system, also known as epicyclic gearing or planetary gearing, 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, orbit the sun gear within a gearbox. These planets mesh…

Energy vs Power: Key Differences, Formula & Examples
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…

Car Suspension System Diagram: Jounce, Rebound & Load Design
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…

Determining Material based on Mechanical Properties
Objective The object of the experiment is to determine the material of an unknown specimen based on the material young’s modulus(E). Young’s modulus is the ratio of the stress to strain in the plastic region of the stress-strain diagram. This mechanical property is material specific. The data which was gathered during this experiment is as…

Why understanding beam bending is important?
What is the importance of beams? The primary function of beams, regardless of the application, is to act as structural elements that transfer loads. In the civil engineering field, beams refer to horizontal elements which symmetrical sections, such as an i-beam. For example, in a building, beams support the weight of a building’s floors above, ceilings,…

Combined Stresses in a Pressure Vessel
Objective To determine the normal stresses in the pressure vessel, and also to observe and material properties of the pressure vessel used. Finally, compare the calculated and measured stresses on the surface of the cylindrical pressure vessel subject to torque while pressurized. Known & Assumptions Materials: The materials required: Technovate Stress Analysis System Model 9800…

What is simple torsion and why is it important?
What is an example of torsion force? An example of a torsional force would be anytime a force acting on an object results in a twisted or rotating motion. This twisting movement happens when an applied torque or force encounters an opposing force which generates shear strain. This opposing force could be a result of…
