Dynamics tutorials: kinematics, kinetics, mechanical systems and mathematical modeling of motion for engineering students.
Moment of Inertia in Plain English Moment of inertia (I) is a measure of how hard it is to start, stop, or change the speed of something that rotates. It is the rotational version of mass. Two things set it: how much mass an object has, and how far that mass sits from the axis…
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…
In the realm of engineering and applied sciences, understanding and modeling dynamic systems are essential skills. When designing control systems, it is imperative to effectively model the dynamics of engineered systems. This model consists of a set of equations, typically differential equations, that depict the system’s dynamics based on the principles of physics. Through this…
Why are the dynamics of mechanical systems important? Dynamics of mechanical systems is the science/ study of motion, aiming to describe natural and technological movements in the simplest way possible. It encompasses all aspects of motion, including displacements, deformations, and static systems where motion appears frozen. In the realm of engineering, understanding the dynamics of…
Crashworthiness refers to a structure’s ability to reduce the number of fatal and serious injuries that occur in an impact/ accident. Most commonly assessed in aviation and automotive safety. Various criteria determine crash safety, depending on impact type and vehicle. Evaluation can be performed through finite element analysis, which is a form of computer-aided engineering…
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…
