Aim: Solving Second order ODEs using Matlab (Simulation of Simple Pendulum) Objectives: To solve second order ODES and to determin the angular velocity, displacement, acceleration of a simple pendulum. Backround: In Engineering, ODE is used to describe the transient behavior of a system. A simple example is a pendulum.…

Objective: To write a code to obtain PV diagram of Otto cycle (Air standard cycle) and to calculate the thermal efficiecy of the cycle using Python. Background: Introduction:   Process: 1)    Intake stroke; a mixture of both air and gasoline are drawn into the engine (5-1) 2)    Compression…

To develop a PYTHON program to simulate the forward kinematics of a 2R robotic arm by simulating the profiles of the angles projected by the two linkages along with the x-axis.  A python script was set-up in sublime and saved to a define folder The matplotlib, math, and numpy modules were imported to the script The…

This is the Python program to calculate drag force against a cyclist. The factors involved are Velocity,Drag coefficient,Frontal Area,Density of air.   import matplotlib.pyplot as plt A=1.75 d=1.12 v=[2,3,4,5,6,7,8,9] cd=0.75 drag_forces=[] for velocity in v: drag_forces.append((0.5*A*d*cd*velocity*velocity))…

Objective: Mathematically construct the functional relationship between the observed dataset and parameter values to Curve Fit.   Introduction: Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints.  It…
