Strength of MaterialsComplementary Shear StressEASY
Choose the correct answer
A
Shear stresses on any plane are zero
B
Shear stresses on perpendicular planes are equal
C
Shear strain equals normal strain
D
Shear stress is proportional to normal stress
Correct Answer
B. Shear stresses on perpendicular planes are equal
Why is this the answer?
Complementary shear: τxy=τyx; shear stresses on perpendicular planes are equal in magnitude.
