The problem assumes that the spring starts from the relaxed length with zero force.

What is force constant of a spring. It is different for different springs and materials. The constant force spring is an excellent device for applications where a constant load is required. In this example a 9000 N force is pulling on a spring.

The spring constant of this spring is 30000 Nm. A constant-force spring unlike an ordinary spring does not obey this rule. As a result of the constant-force springs physical design the power with which it recoils remains constant.

Now that we know that k is the spring constant we will look at spring constant definition. The force at the maximum compression is the peak force mg. 58K views View 2 Upvoters.

The figure shows a graph of the balls position as a function of time. For example if the force. Some of the many applications of constant force springs are in counterbalances door closers cable retractors hose retrievers tool head returns cabinet furniture components gym equipment hair dryers toys electric motors appliances.

The spring constant k is a measure of the stiffness of the spring. The law is named after 17th-century British physicist.

Constant-force spring From Wikipedia the free encyclopedia An ideal constant-force spring is a spring for which the force it exerts over its range of motion is a constant that is it does not obey Hookes law. In standard constant force spring behavior the user must first overcome the springs full load by extending the spring beyond 125 times its diameter. A 240-kg ball is attached to an unknown spring and allowed to oscillate.

As a result of the constant-force springs physical design the power with which it recoils remains constant. Force constant mainly means spring constant in physics which ultimately refers to Hookes law. So 935874 newtons is the total force acting on the spring.

Hookes 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 distancethat is F s kx where k is a constant factor characteristic of the spring ie its stiffness and x is small compared to the total possible deformation of the spring. In order to do so the diameter of the coil must remain constant or close to constant. The spring is placed inside a smooth tube that is 17 cm tall.

In most types of springs the force exerted when that spring is compressed and then relaxed is proportional to the distance that it has been stretched. Also the displacement is 300 cm 030 m. However constant force spring systems are still able to approximate constant force.

The spring constant units are given as Newton per meter. If you think about what this means in terms of units or inspect the Hookes law formula you can see that the spring constant has units of force over distance so in SI units newtonsmeter. The larger the spring constant the stiffer the spring and the more.

It means that the spring pulls back with an equal and opposite force of -9000 N. The force constant of a spring is 300 Nm and its unstretched length is 17 cm. Hookes law is a principle of physics that states that the force F needed to extend or compress a spring by some distance X is proportional to that distance.

Thus putting the values in the above formula we get K frac-9000030 ie. The spring constant shows how much force is needed to compress or extend a spring or a piece of elastic material by a given distance. A constant-force spring unlike an ordinary spring does not obey this rule.

The constant force spring is an excellent device for applications where a constant load is required. Constant-force springs are therefore useful in many applications where a consistent recoil force is important. So the average force is 12 of the peak force 12 m g.

The spring force is F the equilibrium position is x o the displacement of the spring from its position at equilibrium is x the spring constant is k. For a given spring and other elastic objects the extension is directly proportional to the force applied. Since k is a constant the relationship between force and distance is linear.

Since 397 cm of spring is resisting this divide that force among the 397 cm and you get a constant force of. Where F represents the restoring force of the spring x is the displacement of the spring and k is known as the spring constant. The spring constant is different for different elastic objects.

In reality constant-force springs do not provide a truly constant force and are constructed from materials which do obey Hookes law.
