What is an air standard cycle? The air standard cycle is a thermodynamic power cycle that converts heat energy into mechanical power by considering air as a working fluid with constant specific heat. In this cycle, the air is the only working fluid that goes through changes in its thermodynamic properties to convert heat…

  Code and comments explaining the code: clear all close all clc %inputs l1= 1.3 l2=1.2 %Array of values for theta1 & theta2. suppressed to prevent printing of %values in the command window theta1=0:6.5:91; theta2=0:6.5:91; %counter set to 1 to initiate for loop i=1; %for loop sets the value of p between 1 to…

A simple pendulum consists of a ball (point-mass) m hanging from a (massless) string of length L and fixed at a pivot point P. When displaced to an initial angle and released, the pendulum will swing back and forth with the periodic motion. By applying Newton's second law for rotational systems, the…

What are Genetic Algorithms? Genetic algorithms are a part of a bigger group of algorithms called evolutionary algorithms and are a learning method inspired by evolutionary biology.    The process of natural selection starts with the selection of the fittest individuals from a population. They produce offspring which inherit…

Implement control logic of a “washing machine” using Stateflow as per given sequence:  If the power supply is available, the system gets activated  If the Water supply is not available, stop the process & indicate through LED Soaking time should be 200s followed by Washing time of 100s. Then rinsing…

Objective: A universal joint (universal coupling, U-joint, Cardan joint, Spicer or Hardy Spicer joint, or Hooke's joint) is a joint or coupling connecting rigid rods whose axes are inclined to each other, and is commonly used in shafts that transmit rotary motion. The main objective here is to perform a Transient structural…

Tesnion Test: Tensile tests are used to determine how materials will behave under tension load. In a simple tensile test, a sample is typically pulled to its breaking point to determine the ultimate tensile strength of the material. The amount of force (F) applied to the sample and the elongation (∆L) of…

A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single point cutting tool to cut the work piece. A planer is similar to a shaper, but larger, and with workpiece moving, whereas in a shaper the cutting tool moves. The most common applications of planers and shapers…
