The instantaneous center of velocity (IC) is a unique reference point which momentarily has a velocity of zero magnitude. Thus, as far as velocities are concerned, the body seems to rotate about the instantaneous center, that is, the velocity of any point on the rigid body is simply the angular velocity of the rigid body times

Real Life Applications: MOS Capacitor is basically a two terminal MOSFET. Beauty of this capacitor is it will be generally used under equilibrium. All the Enhancement properties of MOSFETs are coming from MOS Capacitor. Why MOSCAP is important? In the GATE point of view, this topic is hot favourite of the GATE committee. In last

Real Life Application A Three point starter is used to start dc shunt motor or dc compound motor. Explanation To understand this we need to realize that high current will flow in dc motors at the time of starting, as the speed is zero and the back emf is zero and thus current is enormously

Real Life Applications: This method is also known as method of load factor design or ultimate load design. The strength of steel beyond the yield stress is fully utilized in this method. This method also provides striking economy as regards the weight of steel since the sections designed by this method are smaller in size

Real Life Application: In active region BJT will act as amplifier and we have assumed that the current gain alpha and beta will be constants with respect to applied voltage, which will not be valid in practicality because as we will apply ac signal in input then voltage in the BJT will keep on changing.

Real Life Application The primary supply of all the world’s electrical energy is generated in three phase synchronous generators using machines with power ratings up to 1500 MW or more. The ability to control power factor makes them an attractive choice. As Synchronous condenser: by varying excitation it can made to operate on lagging or

Introduction to Heat Transfer This lecture is short description of the subject of heat transfer. It gives an idea of the scope of the subject, its applications and discusses a basic difference between the three mechanisms of heat transfer through examples. Scope: Heat Transfer vs. Thermodynamics Whenever a process occurs, it involves some kind of

Real Life Applications: We all are using voltage reference circuits (Voltage regulators) in real life. This is because of breakdown in diodes and some time it will exceed maximum power handling capacity of the device then it will burn out. So it is important to see exactly what is happening inside the device. Explanation: Diode

Working Stress Method: The stresses in the member is obtained from the working loads and compared with permissible stresses. Working Stress method will lead to large FOS and over-sized sections, thus the sections will be uneconomical. WSM is still being used in special structures such as water tanks, bridges, chimneys in India. Ultimate Load Method:

Real Life Application Frequency analysis plays an important role in hydraulic engineering applications such as those concerned with floods, for example in construction of Dams it is necessary to find out the probability of occurring an extreme flood. Explanation To understand the concept with clarity it’s important to understand two things:- 1. Probability 2. Return
