Shafts are widely used mechanical components which are used to transmit power through devices such as gears and pulleys. The shaft is generally acted upon by bending moment, torsion and axial force. Design of shaft primarily involves in determining stresses at critical point in the shaft that is arising due to aforementioned loading. The friction and other losses in this type of power transmission equipment are comparatively very low. In this paper we use a software called “MATLAB” to write a program to design a shaft. MATLAB is extensively used for scientific and research purposes. It is accurate and also has a number of built in functions which makes it versatile. Still MATLAB is not effectively being used in mechanical engineering field. At present the MATLAB code for design of shafts doesn’t exists. Our MATLAB code works for all solid shafts mounted with number of pulleys and gears. The program is user friendly one & when executed it ask the inputs and performs the necessary design calculations and gives necessary output values.
