REVISION OF ENGINEERING MECHANICS

ENGINEERING MECHANICS

Deals with the principles of mechanics along with their application to engineering problems. Divided into two parts: 

STATICS 

DYNAMICS

Statics is the branch of Engineering Mechanics deals with force and its effects while acting upon the bodies at rest.

Dynamics is the branch of Engineering Mechanics deals with force and its effects while acting upon the bodies in motion. It is further divided into two groups.

KINETICS 

KINEMATICS

FORCE

An agent responsible for produce (tends to produce) or destroy (tends to destroy) the motion of a body.

👉 can change the motion of a body

👉 Retard the motion of a body

👉 Can balance the forces already present 

👉 Rise in internal stress in a body

CHARACTERISTICS OF A FORCE

👉 Magnitude of force

👉 Line of action of force

👉 Nature of force ( push or Pull)

👉 The point at which force is acting

RESULTANT FORCE

A single force produces the same effect as produced by all other forces acting on a body.
