2.4 BASICS OF MECHANICAL AND CIVIL ENGINEERING, , at, 4, wv, , RATIONALE, , Apart from the common core subjects, some engineering subjects are included in the diploma, course of electrical engineering. One of these subjects is Elementry Mech. Engg. to impart, some necessary knowledge and skill about mechanical nature. Inclusion of the subject is, further justified by the fact that in practical field, any job of electrical and civil technician is, intermingled with either civil or mechanical engineering. As such the relevant basic topics of, these disciplines are included in the content of the subject., , Some study exercises along with some field work have been suggested to give feel of jobs, and equipments involved., , LEARNING OUTCOMES, After undergoing the subject, the students will be able to:, , e Apply Thermodynamics Laws., , e Use of various energy sources., , © Solve basics problems related to fuel and combustion., , e Have an idea of loading on machine components., , e Explain the application of different types of bearings., , e Explain the uses of different types of gears and springs., , e Explain the working principle of different lubrication systems., , SECTION A - MECHANICAL ENGINEERING, DETAILED CONTENTS, 1.
