Technician A says that the torque applied to the head bolts is the same as the clamping force on the gasket. Technician B says that the clamping force is the force actually applied to the surfaces of the gasket. Who is correct? A. Technician B B. Technician A C. Neither Technicians A nor B D. Both Technicians A and B

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.

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.
