What is a stretching force?

As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force. The farther the material is stretched or compressed, the greater the elastic force becomes.

What is the force constant of a spring?

As per the Hooke’s Law, if spring is stretched, the force exerted is proportional to the increase in length from the equilibrium length. The formula to calculate the spring constant is as follows: k= -F/x, where k is the spring constant. F is the force and x is the change in spring’s length.

What is the stretching force of a spring called?

That linear dependence of displacement upon stretching force is called Hooke’s law. When a force pulls a spring, the spring stretches. The extension of the spring is directly proportional to the pulling force. This is Hooke’s Law.

Which name is given to the force that stretches a spring?

In mechanics, the force applied per unit area is what is important, this is called the stress (symbol σ). The extent of the stretching/compression produced as the material responds to stress is called the strain (symbol ϵ).

How much force is required to stretch a spring 4 inches?

a force of 10 pounds is required to stretch a spring of 4 inches beyond it’s natural length. assuming hooke’s law applies, how much work is done in stretching the spring from its natural length to 6 inches beyond its natural length. what i did so far:

How do you find the work required to stretch a spring?

Using Hooke’s Law to find the work required to stretch a spring. Eighteen foot-pounds of work is required to stretch a spring 4 inches from its natural length. Find the work required to stretch the spring an additional 3 inches.

How do you calculate spring force from Hooke’s law?

Spring force equation. Knowing the Hooke’s law, we can write it down it the form of a formula: F = -k*x. where: F is the spring force (in N), k is the spring constant (in N/m) and.

What is Hooke’s law of elasticity?

Hooke’s law deals with springs and their main property – the elasticity. Each spring can be deformed (stretched or compressed) to some extent. When the force that causes the deformation disappears, the spring comes back to its initial shape, provided the elastic limit was not exceeded.
