Learning Goal:
To use fundamental geometric and statics methods to determine the state of plane stress at the point on an element of material that is rotated clockwise through an angle from the in-
plane stress representation of the point.
The state of in-plane stress at a point on an element of material is shown. Let o,
the same point that is rotated through an angle of 0-35
45.0 ksi, o, 19.0 ksi, and Ty 12.0 kai. Use this information to represent the state of stress of
