Hookies law applies to a great many materials including wood , glass and most metals provided elastic limit is not exceeded in each case.However, if the spring is replaced with a piece of wood or a steel bar, any extensions produced would be far too small to measure using the existing millimetre scale.

What Robert Hooke's law is?
Robert Hooke discovered the law of elasticity. The law is that the extension of the spring is equivalent to the force applied.
Which state of matter obeys Boyle's law?
The state of matter that obeys Boyle's Law is gas. This law states that "For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional".
What is plastic behaviour of a material under load?
plastic behavior is the region where we have the non linear curve and upon unloading the shape can not be recovered.at this region,the stress is not directly proportional to strain i.e Hooke's law is not obeyed
Does hooke's law apply to elastic materials or to inelastic materials?
Why do we say that a spring is Elastic
Does a sled use newtons second law?
Every single object that exists obeys ALL of Newtons Laws
Materials that are said to be hookean?
A hookean material obeys Hooke's Law: stress is proportional to strain in a linear fashion and when stress is removed strain returns to zero. Most materials behave this way until yield is reached but before that are readily analyzed. Mathematically, where s is stress and e is strain and E the elastic modulus material constant, we have s = Ee
What is the benefits of knowing Young's Modulus for concrete?
Young's modulus describes the relationship between stress (sigma) and strain (epsilon) in a material that obeys Hooke's law. Concrete is such a material and knowing this property allows one to plan and design the use of concrete as a building material safely.
According to Hooke's law describe a graph of force versus displacement for an elastic spring?
The spring obeys Hooke's law for all displacements. Hooke recognized this, and his law applies only while the displacement stays within the "elastic limit" for the spring. Within that range the graph is a straight line through the origin.
Does an extension spring behave according to Hooke's law?
Yes it does, unless you stretch it so much that it yields
How is hooke's law releted to torque wrench action?
Torque wrenches depend on a modern generalisation of Hooke's Law. The deformation of an elastic material (even the steel out of which parts of a torque wrench are made) is proportional to the stress to which it is subjected. When you use a torque wrench part of it follows the thing your turning and part of it does not. That part of the torque wrench twists slightly; it's being deformed and obeys Hooke's Law. The more twist, the more torque is being applied. The needle amplifies the amount of twist so that you can read the torque on the gauge.
What was the rule for Hooke's law?
From Wikipedia, the free encyclopediaIn mechanics and physics, Hooke's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it. Many materials obey this law as long as the load does not exceed the material's elastic limit. Materials for which Hooke's law is a useful approximation are known as linear-elastic or "Hookean" materials. Hooke's law in simple terms says that strain is directly proportional to stress.Mathematically, Hooke's law states that
In what field of science is Hooke's law applied?
Hooke's law of elasticity is used to describe how a material body is deformed by stress (at its simplest). Imagine a weight suspended on a spring. The spring will lengthen according to Hooke's law. The law has application in civil and mechanical engineering wherever materials are placed under stress.
What does the percentage of elongation of a test piece under a tensile load indicate?
The change in length of a material under loading can be used to calculate the strain the material has undergone. When stress is plotted against strain, the gradient of the straight line portion of the stress strain curve is equal to Young's Modulus, a type of axial stiffness applicable to a material that obeys Hooke's law at stresses below the yield strength of the material.
What does Hooke's law depend on?
Within the elastic limit of the material, a springs deformation is proportional to its loading.
Will Hooke's law still hold when large forces are applied?
Every elastic material has a maximum force it can stand; beyond that force, it will start getting deformed or break, and Hooke's Law will no longer hold.
Who discovered hooke's law?
Robert Hooke discovered the law.
What law states that the force on a spring is directly proportional to the stretch of the spring?
That's called Hooke's Law.That's called Hooke's Law.That's called Hooke's Law.That's called Hooke's Law.
