Finding Spring Constant

In summary, the task is to design a spring that will give a 1160 kg satellite a speed of 2.85 m/s relative to an orbiting space shuttle, with a maximum acceleration of 5.00g. The mass of the spring, recoil kinetic energy of the shuttle, and changes in gravitational potential energy are all negligible. To determine the force constant of the spring, the formulas f = k (l - l0) and EPE=1/2 kx can be used, as well as the equation F=ma since the maximum acceleration is given. The distance the spring must be compressed can be calculated using the formula l - l0.

You are asked to design a spring that will give a 1160 kg satellite a speed of 2.85 m/s relative to an orbiting space shuttle. Your spring is to give the satellite a maximum acceleration of 5.00g. The spring's mass, the recoil kinetic energy of the shuttle, and changes in gravitational potential energy will all be negligible.

What must the force constant of the spring be?

What distance must the spring be compressed?

I don't know where to start with on this one. Can someone please start me off with this one.

f = k (l - l0) would be a good place
 
  • #3
Also, you might want to try EPE=1/2 kx
 
  • #4
Since you are also given a max acceleration, F=ma would be worth noting as well.
 

What is a spring constant?

A spring constant, also known as force constant or stiffness, is a measure of how much force is needed to stretch or compress a spring by a certain distance. It is represented by the letter k and is measured in units of force per distance, such as Newtons per meter (N/m).

How is the spring constant calculated?

The spring constant can be calculated by dividing the applied force by the displacement of the spring. This can be written in the formula k = F/x, where k is the spring constant, F is the applied force, and x is the displacement of the spring.

What factors can affect the spring constant?

The spring constant can be affected by several factors, including the material and shape of the spring, the number of coils, and the way the spring is attached to other objects. Temperature and external forces can also affect the spring constant.

What is the significance of finding the spring constant?

Finding the spring constant is important as it helps to understand the behavior of a spring under different conditions. It can also be used to predict how much force is needed to stretch or compress a spring, and to design and control the movement of objects with springs.

How can the spring constant be experimentally determined?

The spring constant can be experimentally determined by measuring the displacement of the spring for different applied forces and then plotting the data on a graph. The slope of the graph will represent the spring constant. This method is known as Hooke's Law.
