Stress is basically the internal resistive for induced inside the material per unit area. This internal resistive force will be induced inside the material only when the material is in equilibrium. Normal stress is the stress induced inside the material when the load is acting perpendicular to area of cross section and shear stress is

Maxima and Minima is a very important concept of calculus. We can use this concept in real life scenario whenever we want to make optimal usage of available resources so that profit is maximized. Explanation To understand the concept with clarity it’s important to have basic idea of derivative, Increasing and Decreasing functions. Derivative in

Real Life Application Torsion occurs in the machine elements of shafts like drive shafts, power shafts of automobiles etc. It also occurs in many other applications where rotatory components are present. This topic helps us to understand to keep the stresses induced to be in safe limits. Explanation To understand the concept with clarity it’s

Superposition Principle: Super position is only valid in linear circuits. So firstly discuss about linearity. Linearity is defined by two principles Homogenity Additivity Homogenity If input is scaled by some constant factor, then output should also be scaled by same constant factor. One more very important fact to justify the homogenity is., if input is

Riser Design 1. When a molten metal is paused into the cavity its temperature then is , much higher than its melting point. 2. Say, if its melting point is 500°C , then its pausing temperature would be around 700°C. 3. This difference between pausing and melting point is known as “Degree of superheat”. 4.

Real Life Application Finding out stress in any component is very important to make sure that the component do not get failed. Anywhere in day to day life where ever stress in the component reaches failure stress then the particular component fails. Explanation When multiple loads are acting on a prismatic bar on different parts

< Real Life Application In this topic, Basics of Electrical Machines, the Principles of Electromechanical Energy Conversion Devices and the Relations between Electric field and Magnetic field are explained whose real life applications are immense. For example, all the DC Machines and the AC Machines are derived from these theories and are being used in

Basic Method of Analysis 1. Nodal Analysis Nodal analysis method is basically sum of two laws. 1. KCL 2. Ohms’s law In this method we will use KCL & Ohm’s law to calculate the node voltages in the circuits. Node → any function where atleast 3 branches will meet is known as anode. Procedure Determine

Real Life Application This concept will be very helpful in choosing the type of material according to the requirement. It also gives a basic idea about semiconductors. Explanation Semiconductors are preferred in case of Electronic devices as it is required to have control over the flow of charge carriers which is unlikely in metals. In

Maximum Power Transfer Theorem: “This theorem is basically implementation of concept of maxima and minima in the network to get the condition for maximum power to be transferred to load”. Any Linear, bilateral network by the Thevenin’s theorem can be replace by single voltage source and series resistance. 1. Load is purely resistive and variable.
