How do you calculate the amount of force required to stretch a spring?
F = -kx. The proportional constant k is called the spring constant. It is a measure of the spring's stiffness. When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position.
What is the spring constant of a spring that needs a force of 3 N to be compressed from 40 cm to 35 cm?
F = k Δx = 100 N / m × 0.01 m = 1 N Page 9 Practice Problem #2 What is the spring constant of a spring that needs a force of 3 N to be compressed from 40 cm to 35 cm? The spring changes from a length of 40 cm to 35 cm, hence it compresses 40 cm – 35 cm = 5 cm Δx = 5 cm = 0.05 m.
How much force is necessary to stretch a spring 0. 5 m?
A 20 N force is required to stretch a spring by 0.5 m .
How to calculate the spring constant?
When a spring is stretched, the force exerted is proportional to the increase in length from the equilibrium length, according to Hooke's Law. The spring constant can be calculated using the following formula: k = -F/x, where k is the spring constant. F denotes the force, and x denotes the change in spring length.

How much force is needed to pull a spring with a spring constant of 20 N m at a distance of 25 cm?
Answer: A force of 5 Newtons is needed to pull this spring a distance of 25 cm.
How do you calculate force in Hooke’s Law?
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.
How do u calculate force?
Force exerted by an object equals mass times acceleration of that object: F = m * a .
What is the stretching force?
Tensional force is a force applied by an object being stretched. The object being stretched might be a rope, a string, an elastic band or a wire. The tensional force of the object is applied on the objects that are stretching it. Tensional force is directed along the stretched object.
What force stretches a spring?
The spring force is called a restoring force because the force exerted by the spring is always in the opposite direction to the displacement. This is why there is a negative sign in the Hooke's law equation. Pulling down on a spring stretches the spring downward, which results in the spring exerting an upward force.

What force in Newtons is required to stretch the same spring?
The units on the spring constant are Newton/meter (N/m). The negative sign in the above equation is an indication that the direction that the spring stretches is opposite the direction of the force which the spring exerts….Hooke's Law.
| Mass (kg) | Force on Spring (N) | Amount of Stretch (m) |
|---|---|---|
| 0.500 | 4.900 | 0.0199 |

How much does elastic stretch?
Using Math: Generally, elastic is stretched between 3-8%, with 8% being used only in parts where you want the garment to “hug” the body (i.e. at the underarm near the armpit). So if you want to use math, then you can measure the length of what is being sewn and reduce it by 5%.
How do you calculate force needed?
Multiply mass times acceleration. The force (F) required to move an object of mass (m) with an acceleration (a) is given by the formula F = m x a.
How much force is in a newton?
One newton is equal to a force of 100,000 dynes in the centimetre-gram-second (CGS) system, or a force of about 0.2248 pound in the foot-pound-second (English, or customary) system.
How do you calculate force?
Force exerted by an object equals mass times acceleration of that object: F = m * a .
How do you calculate force example?
The force (F) required to move an object of mass (m) with an acceleration (a) is given by the formula F = m x a. So, force = mass multiplied by acceleration. As an example, if the mass of the object is given to be 3 pounds, you'll need to convert those pounds to kilograms.
How do you calculate stretch factor?
To stretch or shrink the graph in the y direction, multiply or divide the output by a constant. 2f (x) is stretched in the y direction by a factor of 2, and f (x) is shrunk in the y direction by a factor of 2 (or stretched by a factor of ). Here are the graphs of y = f (x), y = 2f (x), and y = x.

How is elastic stretch measured?
Unwrap a length of your elastic and mark a length of elastic based on your measurement. Then, cut the adjusted measurement. For example, if your waist measurement was 30 inches (76 cm), subtract 2 inches (5.1 cm) to get an elastic measurement of 28 inches (71 cm).
How do you stretch elastic?
Iron the elastic. With the damp cloth on top of your elastic band and your iron on the highest setting, iron over it. Iron for 10 seconds and then let sit for 10 seconds. Continue doing so for 5-10 minutes. This will help your pants fit because as the elastic heats, it will heightens the breaking weight.
How do you calculate the force needed to move an object?
Multiply mass times acceleration. The force (F) required to move an object of mass (m) with an acceleration (a) is given by the formula F = m x a. So, force = mass multiplied by acceleration.
How do you calculate force in Newtons?
The force formula is defined by Newton's second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.
How do you solve for force?
Learning the Formula. Multiply mass times acceleration. The force (F) required to move an object of mass (m) with an acceleration (a) is given by the formula F = m x a. So, force = mass multiplied by acceleration.
What is the formula for force?
It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.
