What is Mechanical Coupling? A mechanical coupling connects the driver and driven shafts and transfers torque between them. Coupling is a very important element in connecting two shafts because it reduces the impact of misalignment between shafts. Fo ...
Mechanical Properties of a Material
Mechanical properties of material define material behavior under external load conditions such as tension, compression, and shear forces. These properties help in the selection of material during product and process design. For example, to draw wire, a ma ...
Types of Heat Treatment Process in Steel?
The heat treatment process has applications to alter the material's mechanical properties. The type of heat-treatment process determines what will change in material mechanical properties. This article covers various types of heat treatment processes with ...
What is Least Count and how to calculate it?
The least count of an instrument has a direct relationship with the measuring instrument accuracy and precision. For example, to measure 6.2 ± 0.25 mm dimension, a ruler is not the right measurement tool. Because the minimum dimension a ruler can measure ...
Accuracy vs Precision: Understand with Example
We use accuracy and precision to evaluate the performance of repetitive tasks or measurements. These terms tell us how accurate and repetitive we are in a repetitive task. Sometimes, we use these terms interchangeably, but they are different and incomplet ...
What is Free Body Diagram and How to Draw FBD?
What is Free Body Diagram ? A Free body diagram or FBD is a graphical representation of the relative magnitude and direction of all the forces acting on a body in given conditions.FBD calculates forces acting on a body in moving and stationary conditi ...
What is Degree of Freedom (DOF) in Mechanics
Degree of Freedom is defined as the minimum number of independent variables required to define the position of a rigid body in space. In other words, DOF defines the number of directions a body can move. The degree of freedom concept is used in kinematics ...
What is Strain in Mechanics – Strength of Material
When an external force is applied, A rigid body changes its size and shape due to internal mechanical stress. We represent this change in length by strain. In this article, we will discuss what is the strain in mechanics? Types of strain and how to calcul ...
Stress-Strain Curve: Strength of Materials
Why do we need Stress Strain Curve? Parts or components in the real world have to withstand external forces during their lifetime. Product designers should consider these external forces with a factor of safety during product design. Therefore new par ...
What is Mechanical Stress : Strength of Material
Internal resistive forces acting in the direction opposite to applied external force resist any change in size and shape of the rigid body. Due to mechanical stress or external forces, a body changes its shape. We can express this change in body ...
