Simply Easy Learning

Created by Er. Himanshu Vasishta, Last Updated 05-Sep-2019, Language:English

Description

Theory of Machines is an applied science of the relationships between geometry and relative motion of the parts of the machine, and concerns to the forces which act on those parts. It involves analysis as well as synthesis. These video classes have been developed based on the latest GATE syllabus and will be useful for Mechanical Engineering students as well as for GATE exams preparation.

Audience

These video classes have been designed for Mechanical Engineering Students specially who are preparing for GATE examination. It will also be helpful for students in preparing them for their Engineering Syllabus.
