Question

what are hooke's laws?​

Answer 1

Answer :

Hooke's Law -

• According to this law, If the deformation is small, the stress and strain is said to be proportional to each other.
• Hence, Stress ∝ Strain.
• So, Stress = k × Strain.
• Here, k is proportionality constant and is called modulus of elasticity.
• This law is valid for most of the materials.

Stress and Strain -

• The restoring force which is opposite to the deforming applied force per unit area is called stress.
• Stress = F/A.
• It is the ratio of change of length/volume/etc. of body to the original length/volume is said to strain.
• Types of stress include tensile stress, compressive stress, hydraulic stress and shearing stress.
• Types of strain include longitudinal strain, shearing strain and volume strain.

Answer 2

Question

what are hooke's laws?

Answer

Hooke's law:

• The strain procuced in a body by the stress applied to it is directiy proportional to the stress within the elastic limit of the body.

• stress ∝strain
• stress = constant × strain
• stress / stain = constant

Hooke's law is applicable to all kinds of deformation and all types of matter i.e., solids, liquids or or gases within certain limit.This limit tells the maximum stress that can be safely applied on a body without causing pepmanent deformation in its length, volume or shape.In other words, it is a limit within which a body recovers its original length, volume or shape after the deforming force is removed.When a stress crosses this limit, called the elastic limit of body is permanently deformed and is unable to restore its original state after the stress is removed.
