Question

Choose the correct one:
1. A shear is equivalent to the
(a). Sum of one extension and one compression
strain in the same direction
(b). Sum of one extension and one compression
strain in perpendicular directions
(c). Sum of two extension strains in perpendicular
directions
(d). Sum of two compression in perpendicular
directions which one correct​

Answer 1

Answer:

b

Explanation:

hiiiiiiiiiiiiiiiiiiiiiiii

Answer 2

A shear is equivalent to the  Sum of one extension and one compression

strain in perpendicular directions (Option B)

Explanation:

• The ratio of displacement to an object's original dimensions due to stress, and is the amount of deformation perpendicular to a given line rather than parallel to it is called shear strain.
• Shear stress(τ) = Tangential Force/ Resisting cross-sectional Area.
• Shear strain can be defined as the ratio of deformation to its original length or shape.
