WSP Mechanical Engineer Interview Questions and Answers

The test was for 1 hr. it contained general topics

Q1. Describe the stress strain curves. tell us about hoop stress
Ans. 
Stress strain curves show the relationship between stress and strain in a material. Hoop stress is the stress experienced circumferentially in a cylindrical pressure vessel.
• Stress strain curves depict how a material deforms under stress, showing the relationship between stress (force applied per unit area) and strain (resulting deformation)

• The curve typically consists of three main regions: elastic deformation, plastic...read more

Q2. Tell us about stresses in a thin cylinder
Ans. 
Stresses in a thin cylinder are caused by internal pressure and can lead to hoop stress and longitudinal stress.
• Stresses in a thin cylinder are primarily caused by internal pressure exerted on the walls of the cylinder.

• Hoop stress is the stress in the circumferential direction of the cylinder, while longitudinal stress is along the length of the cylinder.

• The formula for hoop stress in a thin-walled cylinder is given by...read more
