What do we do in environmental engineering?

We want to discuss in this article why we need to engineer nature. Everything was working so fine on the self-sustained model. You know that nature designed itself to sustain

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 is BOD? Definition, effect and measurement

To run your system you need oxygen and food. Similarly, micro organism also needs oxygen to consume food? So, the amount of oxygen required by the microorganisms to consume the
