Two technicians are discussing shot peening. Technician A says that larger shot hits a part with more impact. Technician B says that parts can be made stronger by shot peening. Who is right?
A)Technician A only
B)Technician B only
C)Both A and B
D)Neither A nor B

Question

Quizplus · Accepted Answer

Technician A is correct because larger shot indeed hits a part with more impact due to its greater mass, which can lead to more significant surface deformation and work hardening. Technician B is also correct because shot peening is a process used to improve the fatigue strength of components by inducing residual compressive stresses on their surfaces, thereby making parts stronger and more resistant to crack initiation and propagation.
