Animating the motion of a Pendulum with damping using a MATLAB program used to solve the pendulum equation and subsequently plot it's location

A model of a rotating shaft was modelled on Solidworks, of total length of 30cm, a shaft diameter of 2cm, with a bearing diameter of 10cm. Alloy steel was assigned as its material and bearing fixtures were applied to the cylindrical faces of the stepped face. Then a frequency analysis was carried out obtain 5 mode shape…

The following MATLAB is code is written to find the final positions and workspace of a 2R robotic arm manipulator. Therefore using the equations: x1= l1*cosd(theta1)y1= l1*sind(theta1) x2= x1 + l2*cosd(theta2)y2= y1 + l2*sind(theta2) where, theta1 = the angle the first link of the robotic arm makes with the ground theta2=…

A Design Study was performed on a Cyclone Seperator stand for different positions of the rectangular stiffner from the top of the stand, with the goal of maximizing the buckiling Factor of Safety. The thickness of the stiffner is 60 mm. The bottom of the Cyclone stand was fixed and the load acting is set to 150 KN. First…

A MATLAB code has been written to obatain the PV diagram and thermal efficiency of an Otto cycle spark ignition piston engine. The Otto cycle is a description of what happens to a mass of gas as it is subjected to changes of pressure, temperature, volume, addition of heat, and removal of heat. The Inputs that will be given…

Intially the CAD model of a flowbench was created, and the valve was fixed at a particular height and a baseline simulation was carried out. The boundary conditions set were static pressure at the outlet and a stagnation pressure of 2 atm at the inlet. A static analysis was carried out. The goals set for the simulation…

A Gas Flow simulation was setup using air at 300K with an inlet pressure of 101325Pa pressure and 110325 as the outlet pressure on a backward facing step. Therefore there was a pressure difference of 10,000 Pa. Three simulations were done with different base grit/mesh sizes. The velocity and pressure plots were obtained.…
