very low informative. u should add more information instead of ur name in 2nd slide.u can do that on 1st slide.3rd and 4th slide totally meaningless. need more information about sear strain due to shear stress.torsional will go if u can explain in ur presentation.good luck!!!

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.
