3. TOPIC
Shear Strain (Due to
Shear Stress and
Torsional Stress)

4. Analysis of The Topic
Shear Strain
Shear Stress
Torsional Stress

5. Shear Stress
Shear Stress
 Is a measure of how much force is taken by an
object of particular size
 Is expressed by
 Is shear force per unit area
 Is defined mathematically
;
F=Force
A= Area
Which is to get larger stress we have to increase
the force and decrease the cross sectional area.

6. Torsional Stress
 A Specific type of Shear Stress in Which One end
of a part is secured while the other end is Twisted

7. Shear Strain
Shear Strain is
• Deformation of a solid body
• Displacement of any plane relative to a second
plane divided by the perpendicular distance
between planes
• Expressed by
• In most engineering cases it is expresses as the %
percent of the original length.

8. Shear Strain Due to Shear Stress

R = Deformation
L = Length of the shaft
