Answer:

D. Both Technicians A and B

Explanation:

Screw joining is one of the most common bonding elements in mechanical designs. This type of joint basically consists of a screw and parts to be joined. For the joint to be performed, it is necessary to apply a preload force to the screw, causing the parts to be compressed (joint force).

Preload force is achieved through the torque applied to the bolt and can be controlled in a variety of ways, including the ways spoken by technicians A and B, shown in the question above.

For this reason, we can say that both technicians are correct.

B is correct. The torque is modified by the pitch and friction resistance of the threads. The clamping force is the resultant force pulling the head to the gasket.
