Relationship

between

the

material

deformation



and

the

internal

forces,


caused

by

the

external

forces
.

deals with
FORCES

and
MOTIONS
.

MECHANICS


is to study
forces

and
deformation

of
solid materials
in force equilibrium.


The mechanics of solids

Deformation Condition


Solid objects(Materials
) deform
due to the internal forces and should


comply with deformation conditions

Material

Properties

are

expressed

by

a

relationship

between



the

internal

forces

and

the

deformations

Force Conditions


Generally include translational forces and rotational forces(moments)


External forces and internal force(moments)


External forces and Internal forces(Stresses)
