Question

define hook's law with examples

Answer 1

it states that with elastic limit stress is directly proportional to strain ......

Answer 2

the law stating that the stress on a solid substance is directlyproportional to the strain produced, provided the stress is less thanthe elastic limit of the substance.A law stating that the stress applied to a material is proportional to thestrain on that material. For example, if a stress on a metal bar of tennewtons per square centimeter causes it to be compressed by fourmillimeters, then a stress of 20 newtons per square centimeter will causethe bar to be compressed by eight millimeters. Hooke's law generallyholds only up to the elastic limit of stress for that material
Hooke's Law states that the amount of deformation of an elastic object is proportional to the force applied to deform it. ... The formula for Hooke's Law is F=kx where “F” is the force applied, “k” is the force constant of the spring, and “x” is the amount of deformation in meters.
