Final answer:
Interference fits, also known as press fits, are the correct answer since they rely on compressive force and friction to hold components together without additional fasteners, welding, or adhesives.
Step-by-step explanation:
Options A (Welding joints), B (Bolted joints), C (Adhesive joints), and D (Interference fits) describe various types of connections used in mechanical engineering and manufacturing. In the context of relying on compressive force and friction at the joint to hold components together without using additional fasteners, welding, or adhesive, the correct answer is D, Interference fits.
Also known as press fits, these are a method for fastening components together by creating a tight fit between two mating parts, such as a metal peg and a hole in a metal block, where one part is slightly larger than the other. The interference fit relies on the deformation of the parts to create a secure connection that can transmit force effectively without the need for additional fastening elements.
