Question

Hoop stress in thin walled cylinder is

• A. longitudinal tensile stress
• B. radial stress
• C. circumferential tensile stress
• D. compressive stress

Answer 1

Answer:

C. circumferential tensile stress

Circumferential stress, also known as hoop stress, is the stress acting along the circumference of a thin-walled cylinder and is generally tensile in nature. It is given by the equation $\sigma_{h} = \frac{PD}{2t}$ Longitudinal stress, which acts along the length, is also tensile, while radial stress, acting in the direction of the radius, is compressive. The equation for longitudinal stress is $\sigma_{l} = \frac{PD}{4 t}$ .
