What is the formula for effective spring constant?
Spring constant can be calculated using Hooke’s Law. 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 a normal spring constant value?
The spring is not stretched beyond the limit of proportionality and it stretches by 15 cm. Calculate the spring constant. The spring constant is 20 N/m.
How to find spring constant with mass?
mass this formula works. Constant k > 0 is a measure of stiffness of the spring. Mu(t)'' = mg + F s acceleration of the mass To determine the force due the spring we use Hooke’s Law. Thus we have second order linear DE mu(t)'' = mg – k(L + u(t)) = mg – kL – k u(t).
1.Can Spring Constant Take A Value Of Zero, or Can It Be Negative?
According to Hooke’s law,F= -kxHere, the negative sign tells us that the force applied by the spring will always be on the opposite side of the for...
2.What Happens To The Value Of Spring Constant When Several Springs Are Connected In Series Or Paral...
When springs are connected in series the force acting on both the springs will be equal, which is in turn equal to the external force. Consider two...
3.What is the Definition of Spring Constant?
The spring constant is that the force insists on stretching or compressing a spring, divided by the space that the spring gets longer or shorter. I...
4. What is the concept of Spring Force?
For the Springs, there is a position at which they are neutral. When they are stretched or compressed, afterward there is a restoring force that wi...
5.What are springs used for?
Scooping a ballpoint pen (one of the notables with a button you can click to retract the ball) and you will discover a spring on the inside. Take a...
What does a spring constant mean?
The spring constant represents the stiffness of the spring; hence it should always have a positive value. If the spring constant is zero, it means that the stiffness of the spring will be zero. It will no longer be a spring as no force will be acting in the opposite direction.
What is the unit of spring constant?
The spring constant unit is in terms of Newton per meter (N/m).
What is the force of a spring?
The load applies a force of 3500N on the spring. Hence the spring will apply an equal and opposite force of – 3500N.
What does the image of the spring show?
The image shows the movement of the spring when force is applied to one side.
What is the spring constant k?
The spring constant, k, is representative of how stiff the spring is. Stiffer (more difficult to stretch) springs have higher spring constants.
What happens if the spring constant increases?
A stronger spring-with a larger value of k-will move the same mass more quickly for a smaller period. As the spring constant k increases, the period decreases. … For a given mass, that means a greater acceleration so the mass will move faster and, therefore, complete its motion quicker or in a shorter period.
How do you find k in Hooke’s Law?
Mathematically, F∝x, where F is the force applied, and x is the extension or compression of the object (usually in metres). Now, F = – kx, where k is the constant of proportionality called the spring constant.
What does F KX mean?
F=−kx. where: x is the displacement of the spring’s end from its equilibrium position (a distance, in SI units: meters); F is the restoring force exerted by the spring on that end (in SI units: N or kg·m/s2); and. k is a constant called the rate or spring constant (in SI units: N/m or kg/s2).
Why is there a negative in F =- KX?
… In Hooke’s law, the negative sign on the spring’s force means that the force exerted by the spring opposes the spring’s displacement.
What is the slope of the straight line W versus X plot?
W = kx. W is the weight of the added mass. Therefore, the spring constant k is the slope of the straight line W versus x plot. Weight is mass times the acceleration of gravity or W = mg where g is about 980 cm/sec2.
What does K stand for in spring constant?
The letter k represents the “spring constant,” a number which essentially tells us how “stiff” a spring is.
How do you find the spring constant k?
Mathematically, F∝x, where F is the force applied, and x is the extension or compression of the object (usually in metres).
What is the force constant?
View this answer. In physics, a force constant is another name for a spring constant, as defined by Hooke’s law. More specifically, it is a proportionality constant…
What does spring constant depend on?
Answer: In dealing with a coil spring the spring constant will depend on the stiffness of the spring material, the thickness of the wire from which the spring is wound and, diameter of the turns of the coil, the number of turns per unit length and the overall length of the spring .
Does constant force mean no acceleration?
Newton’s second law says that when a constant force acts on a massive body, it causes it to accelerate, i .e., to change its velocity, at a constant rate. … In this case, the constant acceleration due to gravity is written as g, and Newton’s Second Law becomes F = mg.
What is the proportional constant of 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 does it mean when a spring is stronger?
A stronger spring-with a larger value of k-will move the same mass more quickly for a smaller period. As the spring constant k increases, the period decreases. … For a given mass, that means a greater acceleration so the mass will move faster and, therefore, complete its motion quicker or in a shorter period.
What happens to the greater the force applied to an object, the greater the extension?
the greater the force applied to an object, the greater the extension - up until the limit of proportionality
Does each spring have the same extension?
Each spring will experience the the total force so will have the same extension and dependent on the total force
