Hooke’s law is the law is named after 17th-century British physicist Robert Hooke. He is first stated the law 1660 .the principle of physics that the force F needed to extend or compress a spring by some distance X is proportional to that distance. F=Kx when K is a constant factor of the…show more content…
(Engineers say "Stress is proportional to strain".) In symbols, F = kx, where F is the force, x is the stretch, and k is a constant of proportionality. If Hooke's Law is correct, then, the graph of force versus stretch will be a straight line.

Tensile testing experiment

Purpose of the experiment:
Tensile testing is one of the most fundamental tests for engineering,and provides valuable information about a material and its associated properties. These properties can be used for design and analysis of engineering structures, and for developing new materials that better suit a specified use.The basic idea of a tensile test is to place a sample of a material between two fixtures called "grips" which clamp the material.
Procedure:
The tensile test was on three different materials, aluminum, steel and brass.
The Aluminum had the highest resilience if compere with the steel or brass it got 5.5mm of extension after the load.
