It states that, extension is directly proportional to the applied force.This applies to an object's deformation only before the elastic limit; from then on it deforms plastically and no longer follows this law.

  • Stress is the measure of the force required to cause deformation.
  • Strain is the measure of the degree of deformation.
  • The ratio of stress to strain is known as Young's modulus. Elastic modulus defines the amount of force required per unit deformation.

    • Elastic potential energy relates to the elastic part of the graph (up to the elastic limit)
    • So we can only consider the force-extension graph up to the elastic limit

    3) The load is added gradually and the extension for each added mass is measured and recorded. 
    4) The weight (force) of the mass is recorded using spring balance and is recorded.
    5) The stress is obtained from formula force/area.
    6) The strain is obtained from formula extension/initial length
    7) A graph of stress against strain is plotted and the Young's modulus is obtained from the gradient of the graph.]]>     2020-05-21 15:14:52 UTC https://padlet.com/danishhzmi/8zshfbedzu47fp7m/wish/587189235     alifahnadiaami1 https://padlet.com/danishhzmi/8zshfbedzu47fp7m/wish/587244104 2020-05-21 15:38:54 UTC https://padlet.com/danishhzmi/8zshfbedzu47fp7m/wish/587244104 alifahnadiaami1 https://padlet.com/danishhzmi/8zshfbedzu47fp7m/wish/587255979 2020-05-21 15:44:09 UTC https://padlet.com/danishhzmi/8zshfbedzu47fp7m/wish/587255979 Spring arrangement and combinations nadhirahiman95 https://padlet.com/danishhzmi/8zshfbedzu47fp7m/wish/588634545 2020-05-22 09:40:09 UTC https://padlet.com/danishhzmi/8zshfbedzu47fp7m/wish/588634545 Formula of strain nadhirahiman95 https://padlet.com/danishhzmi/8zshfbedzu47fp7m/wish/588640270
