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

At a certain point in a stressed body, the principal stresses are fx=80 MPa and fy=-40MPa. Determine the normal and shearing stresses on the plane whose normal is at +30 degrees with the X-axis.
