Thousands of types of metal grades are available on earth. Different metal and their alloys have different physical, chemical, and mechanical properties. This article covers various types of metals & alloys and their applications. Different Types ...
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 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 Poisson’s Ratio: Definition, Formula, Examples
When we apply an external force on a part, its length changes in the direction of the applied force and perpendicular to the applied external force. This change in length in the direction perpendicular to the applied force is due to the Poisson effect. I ...
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 ...
Why 2nd and 4th angle Projection is not Used
Second and fourth angle projection systems are not used to draw engineering drawings because of the limitation of overlapping projection views. In this article, we will discuss in detail the limitations of the 2nd and 4th angle projection systems. To unde ...
