Shear Stress Flashcards
1
Q
Shear Modulus (of Elasticity/rigidity)
A
τ = Gγ
τ = shear stress
G = Modulus of Elasticity
γ = shear strain
2
Q
τxy
A
x = stresses exerted on a surface perpendicular to x
y = indicates the direction of the stress
3
Q
when is a shearing stress is a positive or negative
A
(axis) (direction) = (sign)
+ - = -
- + = -
+ + = +
- - = +
