SCIENCE OF MECHANICS

Mechanics

Statics Dynamics

Deals with motion, time and

forcesDeals with stationary systems

Deals with system that

change with time

producing it

Class 1 4

TERMINOLOGY

• Machine

• Mechanism

• Kinematic chain

• Rigid body

Definition:Combination of resistant bodies so arranged that by their means the mechanical forces of nature can be compelled to do work accompanied by certain determinate motions

Definition:Assemblage of resistant bodies, connected by movable joints, to form a closed kinematic chain with one link fixed and having the purpose of transforming motion.Definition: When several links are movably connected together by joints, they are said to form kinematic chain. Definition:The parts connected to create kinematic chain are assumed to be rigid

Class 1 5

TERMINOLOGY

• Link

• Kinematic pair or joint

Definition:A Rigid body is called as link

Definition:Connection or joints between the links
