Potential energy is the energy that an object possesses due to its position or configuration within a force field. It represents the capacity of an object to do work based on its position, condition, or state. Potential energy is measured in joules (J), which is the standard unit of energy in the International System of […]

Kinetic energy (KE) is the energy possessed by an object due to its motion. In mechanical engineering, kinetic energy is a fundamental concept used to describe the energy associated with moving objects.  This means that an increase in velocity results in a larger increase in kinetic energy compared to an increase in mass. Conversely, decreasing

Hooke’s Law states that the force (F) exerted by a spring is directly proportional to the displacement (x) from its equilibrium positionHooke’s Law states that the force required to stretch or compress an elastic object is directly proportional to the amount of deformation. It describes the linear relationship between force and displacement within the elastic

To calculate linear velocity, you need to know the angular velocity (ω) and the radius (r) of the rotating object. Linear velocity (v) is the speed of a point on the edge of a rotating object as it moves in a straight line. It’s a fundamental concept in rotational dynamics and is used extensively in

Angular velocity is defined as the rate of change of angular displacement (dθ) with respect to time (dt). Angular velocity (ω) is a measure of the rate of change of angular displacement with respect to time. It describes how fast an object is rotating or how quickly its angular position is changing. Mathematically, it can

The Moment of Inertia of a rigid body about a given axis is the sum of the products of each particle’s mass and the square of its distance from the axis of rotation. The Moment of Inertia is measured in kilogram-square meters (kg·m²). The moment of inertia plays a crucial role in rotational dynamics, governing

Conduction heat transfer occurs when thermal energy is transferred from a hotter region to a cooler region within a solid material or between two solid surfaces in direct contact. It’s governed by the temperature gradient across the material and the material’s thermal conductivity. The formula for conduction heat transfer through a material with uniform cross-sectional

Convection heat transfer occurs when a fluid’s motion, caused by density differences due to temperature variations, results in the transfer of thermal energy between a solid surface and the fluid. It’s commonly observed in natural phenomena such as ocean currents, atmospheric circulation, and the cooling of a hot object in air. The formula for convection

Poiseuille’s Law states that the volumetric flow rate (Q) of a Newtonian fluid through a cylindrical pipe is directly proportional to the fourth power of the pipe radius (r) and the pressure gradient (ΔP), and inversely proportional to the viscosity (μ) and the length of the pipe (L). Poiseuille’s Law describes the relationship between flow

The Steady State Mass Transfer Equation states that the mass transfer rate (˙m˙) is proportional to the concentration gradient (dc/dx) and the cross-sectional area (A) perpendicular to the direction of mass transfer. The Steady State Mass Transfer Equation describes the rate of mass transfer through a medium under steady-state conditions.  It’s commonly used in chemical
