Force Exerted by Contracting or Stretching a Material
Any strain exerted on a material causes an internal elastic stress. The force applied on a material when contracting or stretching is related to how much the length of the object changes.
Force Exerted by Contracting or Stretching a Material formula
\(\large{ F = \frac { \lambda \;A\; l_c } { l_o } }\) |
Where:
\(\large{ F }\) = force exerted
\(\large{ l_c }\) = change in length
\(\large{ l_o }\) = origional length
\(\large{ \lambda }\) (Greek symbol lambda) = modulus of elasticity
\(\large{ A }\) = origional area cross-section through which the force is applied
