Question

write hooke's law when an object is under tension or compression ​

Answer 1

Answer:

stress is equal to strain

Explanation:

• according to Hooke's law stress = strain

Answer 2

Hooke's law

Explanation:

Hooke's law;

According to Hooke's law ,the force required to elongate a elastic object is directly proportional to the extension in that objects. This law is given by Robert Hooke in 17th century.

If the elastic object is spring ,then

F = - K x

Where ,

F=required force

K=Spring constant

x= Extension or compression in the spring

Hook's law can also be explained as follows:

According to Hook's law , stress is directly proportional to the strain up to elastic limit of material.

Stress = Strain X Modulus of elasticity

σ = E ε

σ ==Stress

E=Modulus of elasticity

ε=Strain
