Explanation:
Basically the operator pulls the trigger, which releases the firing hammer, and strikes the firing pin making the gunpowder ignites.
When the in-plane shear stress is at its highest, it is true that the normal stresses are equal.
Their combined value is σn+σt.
<h3>What is in-plane shear stress?</h3>
- 6.3 ksi is the maximum in-plane shear stress. 10.2 ksi is the maximum out-of-plane shear stress.
- By examining Mohr's circle, we may understand why out of plane shear stress is the highest.
- Maximum in-plane shear stress is indicated by the inner blue circle radius (6.3 ksi).
- Maximum shear stress planes are 45 degrees from the major planes.
- The principle stress is the highest stress that may be created in a plane, and the principal stress refers to the principal plane when shear stress is zero.
The complete question is:

a) They are equal.
b) They are zero.
c) Their sum is equal to σn+σt.
d) They are maximum.
e) They are equal to shear stress.
