Answer (Detailed Solution Below)
Detailed Solution

Brittle material under tension
- Brittle materials are very weak in tension. Brittle materials fail due to the separation of particles along the surface which is at 90° to the direction of load.
Brittle material under compression
- Brittle materials are strong in compression, therefore, failure is due to shear the plane to failure is at 45° from the axis of the shaft.
Ductile material under compression
- They fail in compression yielding. Failure plane is at 90° to the compressive load in compression yielding, bulging of material occurs.
Ductile material under tension
- As ductile material strong is in tension, therefore failure is due to shear, the plane of failure is at 45° from the axis of the shaft, such failure is known as cup and cone failure.
