(8)1.1 Introduction
- Consider a diving board as an example of a deformable body
(9)(10)1.1.1 Strength of materials
• A branch of mechanics
• It studies the relationship of
– External loads applied to a deformable body,
and
– The intensity of internal forces acting within the
body
• Are used to compute the deformations of a body
•
Strength of Materials
is a field of study that
determines
strength, stiffness, & stability
