A single crystal was loaded under tension such that the applied stress is 200 MPa, the angle between the slip direction and the direction of the applied force is 30o and the angle between the normal of the slip plane and the direction of the applied force is 20 o. The crystal just yielded. Which of the following statements cannot be true?

Question

Answer

The crystal would still have yielded if the angle between the normal of the slip plane and the direction of the applied force was reduced to 10°

Answer

The crystal would still have yielded if the angle between the slip direction and the direction of the applied force was reduced to 20°

Answer

The critical resolved shear stress of the crystal is above 163 MPa.

Answer

The critical resolved shear stress of the crystal is below 163 MPa.

Answer

The crystal would still have yielded if the applied stress was increased to 220 MPa.
