Answer #1

Strain.

A change in shape due to the application of a force is a deformation.

The ratio of the change in length to its original length or initial resting length is defined as strain. it is unitless quantity, while the ratio of force to its area is refered to as stress, its unit is N/m2

Acute strains are caused by stretching or pulling a muscle or tendon. Chronic strains are the result of overuse of muscles and tendons, through prolonged, repetitive movement. Not getting enough rest during intense training can cause a strain.

A sprain is caused by an injury that stresses a joint and overstretches or even ruptures supporting ligaments. This can happen from a fall, twist, or blow to the body

The region in which the material deforms permanently is called the plastic region

A mad scientist decides to perform an experiment on the tensile strength of living bone. With each change in stress (measured in MPa), he records the strain on the bone and obtains the following data. At 91 MPa the bone fractures and breaks.
