Concept explainers

Stress transformation

The term stress indicates the measure of internal forces that develop due to an external force's application on an object. When a specific external force is applied to an object, internal stress generates in the material. The value of stress can obtain by taking the ratio of the externally applied force and cross-sectional area of the object. There are different types of stress depending on the type of external force.

Question

A faucet is stuck, and a person uses their hand to try to get it
to move. They apply a force F = 100 N and simultaneously
apply a torque T = 5 N·m. What is the state of stress at point
A and at point B of the cross section taken at a-a? Take the
angle 0 to be 45 and the diameter of cross-section to be D =
25 mm. The geometry and axes are as specified in the figure
and parameter table. You can assume the hand acts like a
rigid object when transmitting the force F to the handle.
