## Stress | Definition, and Types

To understand the stress, let’s do one demonstration. Pick the eraser on your table and try to compress it. When you release the pressure, the eraser returns to its original

## Stress Transformation | Derivation and Application

To understand what stress transformation is and why it is needed, let’s perform a demonstration. Take a piece of chalk and try to twist it from both ends, as shown

## Eccentrically loaded columns| Kern of the section

When you load the column about its axis means the action line of load and the centroid of the column are coinciding then it is called the cocentrically loaded column.

## Euler’s critical load for fixed-free column

To understand this situation let’s try to hold the scale as given in the figure. This time hold the column from one end only. You may feel the difference in

## Euler’s critical load for fixed-pin column

When you hold the scale from one end and just support it from the other end with finger (you can refer the figure). The scale behavior will change as the

## Euler’s critical load for fixed-fixed column

The column behavior changes with the end condition. To demonstrate this, pick one piece of wire or the scale. Assume this as your column. In the first case, hold the

## How to draw shear force and bending moment?

When you apply the load in the scale, as shown in the figure, you are applying a transverse load in the scale. These transverse load in the scale causes the

## What are the physical and mechanical properties of steel?

Did you know that having a solid grasp of steel’s physical and mechanical properties is the key to making informed decisions when it comes to selecting the right material and

## What is equilibrium? | Stable and unstable equilibrium

To understand equilibrium, let’s do some simple demonstrations. First, pick any bottle near you (mineral water bottle, cold drink bottle). Then, try to put it on the table in three

## Buckling of Long column| Euler’s critical load

Put the paper on the table and try to push the paper from both sides. What will you find? You will find that when you push the paper, the mid
