Question
The hoop stress in a thin-walled cylinder is given by , which is actually a _________.
- a. Shear stress
- b. Radial stress
- c. Longitudinal stress
- d. Tangential stress
Solution
The equation for hoop stress in a thin-walled cylinder is given by:
where:
- is the hoop (or tangential) stress,
- is the internal pressure,
- is the radius of the cylinder,
- is the wall thickness.
Based on this definition, hoop stress specifically measures the stress acting in the tangential direction of the cylinder wall. It describes how the cylinder material reacts to internal pressure.
Answer:
The correct option is d. Tangential stress.
