Youngs Modulas

Purpose to determine the Youngs Modules
Background/ establishment
Certain springs can stretch so far, for an example all normal person would know that rubber bands can stretch, scarcely if asked if a thread can stretch the answer would be probably no. According to the Youngs modulus, when a rigid corporeal are subjected to a great force, at that place is a permanent deformation. However if the somatic is subjected to a position focal point or force per unit area the material will response with a particular strain or deformation.
If the nisus is in a dwarfish amount the material is very likely to return back to its original shape. If the stress is too great, it would permanently deform. So therefore high levels of stress would be undeniable to strain the thread
The equation confrontation stress is force divided by area of sail role.
And the equation for stain is change of extension divided by original length.




The equation for the young modulus is
Elastic has the following properties
* It has got ductile memory it can return to its original shape afterward it has been subjected to stress
* It is sound as a huge bendable stress is needed to break it
* Flexible, only a small stress is needed to change its extension and it is not effortful to change its shape ]#
A thread has the following properties
* It is strong as a huge elastic force is needed to break it
* Stiff it needs a large tensile stress for the extension to change

Hypothesis
When the plentifulness of the slotted mass increases, the divergence of the end of the elastic/thread will also increase. scarce not so much for the thread compared to the elastic.
Variables
Manipulated: mass of the slotted mass
Responding: deflection of the elastic/ thread
