Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Stretching beyond the YIELD POINT causes a structure to tear or break is called ____
A
Shear
B
Tension
C
Compression
D
Bending
Explanation: 

Detailed explanation-1: -Tension is a force associated with the pulling of an object such as a rope, cable, or chain. It is very similar to elastic potential energy. Once an object is stretched out and put under tension it will naturally return to its relaxed length as soon as it is free of this force.

Detailed explanation-2: -The deformation or elongation of a solid body due to applying a tensile force or stress is known as Tensile strain. In other words, tensile strain is produced when a body increases in length as applied forces try to stretch it.

Detailed explanation-3: -The yield strength anomaly is also referred to as the “yield stress anomaly.” It is usually quite difficult to determine the exact point at which yielding begins, which is why in practice a proof stress is used.

Detailed explanation-4: -The yield point is the maximum stress a material can endure beyond which it begins to permanently deform and is unable to return to its original dimensions. Whereas, tensile strength is the maximum stress on a material before it fails and, literally, breaks.
