Theory of Vibration

Theory of Vibration The way material vibrates under given condition is an important aspect of design of civil structures or mechanical equipment. Historically unexpected failures of bridges and columns have happened because designers did not consider effect of vibration. In this tutorial you will understand fundamentals of vibration and will learn how to apply it in mechanical / civil design you undertake.

Electrical Transformer, How it works?

Electrical Transformer, How it works?

Transformers are capable of receiving AC power at one voltage and delivering it at another voltage. In this article, we will go through the working and construction of a 3 phase transformer by starting from its simplest form. We will also understand what power transformer is and how it is constructed.
