Circle the correct word(s) in brackets to complete each sentence. i) Hooke's Law works for ( springs only / all materials / some materials ).
ii) Hooke's Law only applies ( up to / over ) a certain force.
iii) The force at which Hooke's Law stops working for springs is
( higher / lower ) than
for most other materials?

i) Hooke's Law works for some materials

ii) Hooke's Law only applies up to a certain force

iii) The force at which Hooke's Law stops working for springs is lower than for most materials

Explanation:

Hooke's Law of elasticity states that the deformation of an elastic material is proportional to the applied for small deformations

The law is applicable to elastic materials whose values of deformation or extension as well as the applied load or stress are expressible by a single real number

Hooke's Law is applicable when the force and the extension of the elastic material are proportional, at larger force, the elastic material is observed to expand more than as expected based on Hooke's Law

The nature of springs is such that its elastic limit is reached by a much lower force than for most materials. Therefore, Hooke's law stops working for springs at a lower force than for most materials.

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
