NATIONAL UNIVERSITY OF SCIENCES AND TECHNOLOGY COLLEGE OF ELECTRICAL AND MECHANICAL ENGINEERING

DEPARTMENT OF MECHANICAL ENGINEERING

SUBJECT: ME-100 ENGINEERING MECHANICS

CREDITS: 3-0

INSTRUCTOR: Saheeb Ahmed Kayani

COURSE OBJECTIVES: This course is intended to familiarize students with basic principles of

engineering mechanics especially statics and to apply them to real world

problems and scenarios. Students will learn how to draw free-body diagrams

and formulate their equilibrium equations, and analyze and determine the

resultant of force systems that include moments and couples, reactions, and

internal loads. Further to this in a brief introduction to dynamics they will learn

to develop equations of equilibrium and motion, and techniques for solving

them for forces and different motion parameters such as displacement, velocity,

and acceleration of particles, rigid bodies, and simple mechanical systems.
