PATHOLOGY

Detailed explanation-1: -Contact force is the type of force that tension and compression are. Contact force is a force that occurs when two objects become in contact with each other. Examples include tension, compression, friction, air resistance, normal force, applied force, and spring forced.

Detailed explanation-2: -This action is called bending. Bending: See It In Real Life. The top side of the metal bar is pulled apart in tension, and the bottom side is squeezed together in compression. This combination of opposite forces produces an action called bending.

Detailed explanation-3: -The compression force results in compressive stresses and tensile force in tensile stresses. Therefore, bending stress is a combination of compressive and tensile stresses due to internal moments.

Detailed explanation-4: -A moment that causes bending is called a bending moment. Bending produces tension and compression inside a beam or a pole, causing it to “smile.” The molecules on the top of the smile get squeezed together, while the molecules on the bottom of the smile get stretched out.
