IGCSE Grade 10 Science Hooke s law
|
When deformation is small, stress is proportional to strain for almost all materials.
An empirical law is one which is induced from observation or experiment.
On the stress-strain curve, on the elastic point, the stress of a material takes place more quickly.
As stress is proportional to strain under the elastic limit. So, few materials don't follow Hooke's law.
Hooke’s law itself states that it is valid only up to the elastic range of the material I.e. only to that limit where the material is behaving elastically.
Rubber is generally regarded as a “non-hook” material because its elasticity is stress dependent and sensitive to temperature and loading rate.
For the 1-D system, the stress will be only in one direction. Lateral stress is for an area while normal stress is of a length.
Hooke’s law states that strain is directly proportional to strain produced by the stress when a material is loaded within the elastic limit.
The factor of safety is the ratio of ultimate stress to permissible stress.
Hooke’s law is valid only when the stress is proportional to the strain, which is only in the proportionality limit.
