2. Engineering mechanics is the foundation of analyzing forces and their effects on physical systems. This
discipline enables understanding how structures and mechanisms respond under various loads,
ensuring safety and efficiency in design. It encompasses the study of both stationary systems and
those in motion.
Introduction

3. Statics

4. Forces and Equilibrium
Statics studies objects in equilibrium, where the sum of all
forces and moments equals zero. Understanding force
vectors and their components allows engineers to predict
how structures hold together under different loading
conditions.

5. Moments describe the tendency of a force to rotate an object about a point or axis. Couples consist of
equal and opposite forces whose moment causes rotational effects without translation. Mastery of
these concepts is crucial for analyzing structural stability and mechanical systems.

6. Structural analysis involves evaluating how various loads affect frameworks and components. It
ensures that buildings, bridges, and machinery maintain stability and resist failure under operational
forces. Key methods include determining internal forces, reactions, and deflections to guarantee safety
and durability in engineering design.

8. Kinematics of Particles
Kinematics focuses on the motion of particles without
considering forces. It describes parameters such as
displacement, velocity, and acceleration to understand how
particles move along paths, enabling prediction and
control of mechanical systems.

9. Kinetics examines the relationship between the motion of particles and the forces causing it. It applies
Newton’s laws to determine the effects of forces on particle acceleration and trajectory, essential for
dynamic system analysis.

10. Work and energy principles relate force application to changes in kinetic and potential energy. This
approach simplifies complex force and motion problems by using energy conservation laws,
streamlining the analysis of mechanical systems and improving design efficiency.
