How to Calculate Forces in a Spring with Hanging Masses?

In summary, the conversation is about spring forces and the formulas for calculating the force acting down on a weight hanging from a spring and the force acting on a falling body with respect to gravity. The speaker is asking for help with these formulas and apologizes for any mistakes due to being a non-mechanical person. The expert is asking the speaker to provide information about the formulas they already know before helping further.

Dear experts,

This is regarding the Spring forces.

A Spring with spring constant 'k' is grounded on the lower end. A weight of 'm1' grams is hanged down from its upper end towards down using a thread length L.

(Q1) Here I would like to know the formula to calculate force acting down toward, due to the hanging weigh.

And at this moment a freely falling body of mass 'm2' is falling on the spring from height H with the help of guiders (to make sure it falls ont the spring).

(Q2) Here I would like to know the formula to calculate the corce acting on the mass 'm2' which will be oppsite to gravity

I am a non mechinical guys, for give me incase of any mistakes :)

Thanks in advance!

Electron

Welcome to PF!

Hi PtrElectron! Welcome to PF! :smile:

Start by telling us what formulas you know about springs (including energy).

(on this forum, you have to do the work! :wink:)
 

FAQ: How to Calculate Forces in a Spring with Hanging Masses?

What is a grounded spring?

A grounded spring is a spring that is attached to a fixed object or surface, such as a wall or ceiling, at one end. This provides a stable base for the spring to stretch or compress when a force is applied to it.

How does the mass affect the spring's force?

The mass attached to the spring affects the force it exerts by changing the amount of stretch or compression in the spring. The greater the mass, the greater the force required to stretch or compress the spring.

What is the formula for calculating the force of a grounded spring?

The formula for calculating the force of a grounded spring is F = kx, where F is the force in newtons, k is the spring constant in newtons per meter, and x is the displacement of the spring from its equilibrium position in meters.

How do I find the spring constant of a grounded spring?

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

Can the force of a grounded spring be negative?

Yes, the force of a grounded spring can be negative if the displacement of the spring is in the opposite direction of the applied force. This indicates that the spring is being compressed instead of stretched.
