What is Engineering Mechanics & Strength of Materials ?
ENGINEERING MECHANICS STRENGTH OF MATERIALS Ø In this we assume that the body is perfectly rigid (the type of material which doesn’t undergo any change in geometry of the body when load is applied). Ø In this we assume that the body is perfectly elastic (the type of material which undergoes change in geometry of the body when load is applied) Ø It deals with the study of external force & their effect on rigid body. Ø It deals with the effect of external force & their effect as internal resting force in bodies. Ø In rigid body, stress will develop but no strain. Ø In deformable bodies both stress and strain will develop. Note- Concept of Ideal body or rigid body is hypothetical and it doesn’t exist.
