How to Calculate Forces in a Spring with Hanging Masses?

AI Thread Summary
To calculate the force acting downward due to a hanging weight 'm1' on a spring with spring constant 'k', the formula is F = m1 * g, where g is the acceleration due to gravity. For the freely falling mass 'm2', the force acting on it when it impacts the spring can be calculated using F = m2 * g, but this force will be opposed by the spring force, which is F_spring = k * x, where x is the compression of the spring. Understanding these forces is crucial for analyzing the system's dynamics. The discussion emphasizes the importance of applying basic physics principles to solve the problems presented. Accurate calculations will help in understanding the behavior of the spring under these conditions.

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

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:)
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
