A drag force is the resistance force caused by the motion of a body through a fluid, such as water or air. A drag force acts opposite to the direction of the oncoming flow velocity. This is the relative velocity between the body and the fluid.The drag force D exerted on a body traveling though a fluid is given…

In this project with the help of a Matlab program we have to determine the workspace of the 2R Robotic Arm. The workspace refers to the possible locations the robot can reach. In order to do this we have to analyze the forward kinematics of the 2R Robotic arm. A 2R Robotic-arm contains 2 links and two rotational joints…

The ordinary differential equation representing the equation of motion of a simple pendulum is `(d^2theta)/dt^2+b/m*(d theta)/dt+g/lsintheta=0`     --------------- eq 1 In the above equation, g = acceleration due to gravity in `m/s^2` L = length of the pendulum in m, m = mass of the ball in kg, b=damping…

Curve fitting is the process of constructing a curve that has the best fit to a series of data points. The curve fits all data points for information or the set of data points. Let us consider a polynomial function `f(x)` now if the function is linear then `f(x)` can be represented as `f(x) =ax+b` now…

In this project, we will determine the global maxima of the stalagmite function in the given search space using genetic algorithm. The stalagmite function is defined as So first we will write a program to plot the stalagmite function  %optimisation of the stalagmite function clear all close all clc %defining the search…

Geneva mechanism, also called Geneva Stop, one of the most commonly used devices for producing intermittent rotary motion, characterized by alternate periods of motion and rest with no reversal in direction. It is also used for indexing (i.e., rotating a shaft through a prescribed angle). The name, Geneva…

NASA  came up with polynomials that can be used to evaluate thermodynamic properties such as `C_p`, H and S. They have also documented the coefficients that are required to evaluate these polynomials for 1000+ species. These polynomials are  Here R is the universal gas constant, T is the temperature The documents…

In this project, we will write a MATLAB program in order to determine the internal member forces of a plane truss. Now let us consider a prismatic bar whose length is L, Area of the cross-section is A, made up of a material of Young's modulus E, subjected to external axial load say P, Now considering the bar to be elastic,…

An Otto cycle is an idealized thermodynamic cycle that describes the functioning of a typical spark ignition piston engine. It is the thermodynamic cycle most commonly found in automobile engines.   Assumptions: 1. Sp. Heat Ratio (γ) = 1.42. Temp. after compression = 2500K3. `P_1`= 101325 Pa4. `T_1`= 400K5.…

The Rankine cycle is a model used to predict the performance of steam turbine systems. It was also used to study the performance of reciprocating steam engines. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing…

A planetary gear set is made up of three types of gears; a sun gear, planet gears, and a ring gear. The sun gear is located at the center and transmits torque to the planet gears, which are typically mounted on a moveable carrier. The planet gears orbit around the sun gear and mesh with an outer ring gear. Planetary gear…

The Piston Assembly Consist of mainly five parts such as Piston itself, Gudgeon pin, Connecting Rod, Endcap, and Crank. it is used in the different mechanical machines such as Internal/External combustion engines, compressors, pumps, and etc. based on Applications such as power-producing device (or) power-consuming…
