Question
The state of stress at a point in a component is represented by a Mohr's circle of radius MPa centered at MPa on the normal stress axis. On a plane passing through the same point, the normal stress is MPa. The magnitude of the shear stress on the same plane at the same point is ________ MPa.
Correct answer
79 to 81
Solution
The equation of a Mohr's circle in the plane is given by:where:
- is the normal stress on a plane.
- is the shear stress on the same plane.
- is the center of the Mohr's circle on the normal stress axis.
- is the radius of the Mohr's circle.
- Center of Mohr's circle, MPa
- Radius of Mohr's circle, MPa
- Normal stress on the plane, MPa
