Hooke's Law

• Elastic is the ability for a material to regain shape after deforming forces are removed.
• Hooke’s Law:

  F=k*e

  F is force in N

  K is the spring constant in newtons per metre. N/m

  E is in the extension in meters, m

  Extension = measured length – original length
• The limit of proportionality is a point beyond which behaviour no longer conforms to Hooke’s law.
• The elastic limit is a point which the spring will no longer return to its original shape when the force is removed.
