EXPERIMENT #7
ELASTICITY
Abstract
The researcher's aim in this experiment is to better understand and collect data on elasticity simulations. The principle of
elasticity is so essential that it can benefit students in their physics classes in particular. Before initiating the simulation, It's a good
idea to learn about the elasticity principle. The simulation is about a tensile test on mild steel, and the aim of the simulation is to
allow the researcher to see what happens to the steel when stress is applied. There is also a stress strain graph, which allows the
researcher to visually examine the deformation of the steel. Moreover, the collected data will be presented in the part's result section,
after which the researcher will examine the procedure for obtaining those data.

,I. Introduction
Elasticity is the measurement of an object's deformation (strain) when a stress (force) is applied. Stress is the amount of
force applied to an object, while strain is the amount by which a material deforms under stress or force, expressed as a percentage
of the final deformation. The natural logarithm of the ratio of the final dimension to the initial dimension is used to calculate true
strain.
The elastic modulus and elastic limit of a material are the two parameters that determine its elasticity. Materials with a high
elastic modulus are difficult to deform; in other words, materials that need a large load to achieve a significant strain. A steel band
is an example. A low elastic modulus is common in materials that deform easily under load, such as a rubber band. When the
tension under a load becomes too heavy, the material does not return to its original shape and size when the load is removed, but
instead relaxes to a new shape and size: The substance takes on a permanent deformation. The elastic limit is the stress at which
a substance stops behaving elastically and becomes permanently deformed.
According to Hooke's law, a spring's stretch value is proportional to the magnitude of the applied force. In contrast, the
spring's reaction force is proportional to the stretch applied.
