## Do springs always obey Hookes law?

Constant force springs, in relation to Hooke’s Law, are often false exceptions. From their title and description, you would expect constant force springs not to follow Hooke’s Law. As mentioned in our constant force springs post, the material making up these springs actually does conform to Hooke’s Law.

**Which law does a spring obey in order to oscillate?**

Hooke’s law

Most springs obey Hooke’s law; the more you stretch the spring, the larger the force. What if the force is not proportional to the displacement? Such a force is called a non-linear force which does not obey Hooke’s law.

**How does Hooke’s law apply to springs?**

Hooke’s law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, Fs = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible …

### What is Hooke’s Law explain?

Mathematically, Hooke’s law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. Hooke’s law describes the elastic properties of materials only in the range in which the force and displacement are proportional.

**Does this spring obey Hooke’s Law How do you know?**

How do you know? No, the spring does not obey Hooke’s law because the graph of F versus is linear.

**Why does a spring oscillate?**

In the spring-mass system, oscillations occur because, at the static equilibrium displacement, the mass has kinetic energy which is converted into potential energy stored in the spring at the extremes of its path.

#### Do Springs oscillate?

Both vertical and horizontal spring-mass systems without friction oscillate identically around an equilibrium position if their masses and springs are the same. Figure 1 below shows the resting position of a vertical spring and the equilibrium position of the spring-mass system after it has stretched a distance d.

**What does Hooke’s law say about springs?**

Hooke’s Law is a principle of physics that states that the that the force needed to extend or compress a spring by some distance is proportional to that distance. This ability to return to a normal shape after experiencing distortion can be referred to as a “restoring force”.

**What is Hooke’s Law explain with diagram?**

In mechanics (physics), Hooke’s law is an approximation of the response of elastic (i.e., springlike) bodies. It states: the extension of a spring is in direct proportion with the load applied to it. Diagram of Hooke’s Law: The extension of the spring is linearly proportional to the force.

## Why is Hooke’s law important?

Hookes law is important because it helps us understand how a stretchy object will behave when it is stretched or compacted. The main component of car shocks are springs, and understanding how the spring will behave (using hookes law) is ideal for enhancing the technology.

**Do springs oscillate?**

**Why do things oscillate?**

Objects oscillate because a force of some sort has been applied on them causing them to move but their movement is limited because they are still constrained by a fixed factor. But since they possess momentum they do not just stop moving immediately.

### How do you calculate Hooke’s law?

Hooke’s Law states that: FS = kx (9.1) Here k is the spring constant, which is a quality particular to each spring, and x is the distance the spring is stretched or compressed. The force FS is a restorative force and its direction is opposite (hence the minus sign) to the direction of the spring’s displacement x.

**When does a material exhibit Hooke’s law?**

The material exhibits elastic behaviour up to the yield strength point, after which the material loses elasticity and exhibits plasticity. From the origin till the proportional limit nearing yield strength, the straight line implies that the material follows Hooke’s law.

**What is the period of oscillation of a spring?**

The oscillation will proceed with a characteristic period, ⌧, which is determined by the spring constant, k, and the total attached mass, m. This period is the time it takes for the spring to complete one oscillation, or the time necessary to return to the point where the cycle starts repeating (the points where x, v,anda are the same).

#### What is Hooke’s law of stress and strain?

Hooke’s Law – Stress And Strain. When force is applied to a material, we know that it either stretches or compresses in response to the applied force. In mechanics, the force applied per unit area is known as stress and is denoted by the symbol σ. The extent to which the material compresses or stretches is known as strain.
