Homework Statement
Hello, I need help with a simple task.
I want to calculate the force which appears when a mass falls on the floor without bouncing.
I have modeled a bicycle crankarm, and I want to calculate the stress in it. In order to do that I need a force.
So I want to know the force made by a man (100kg) falling from 0,5 meter directly on the pedals.
Homework Equations
I figured it could be calculated this way:
F=I=m∙a
I=m∙Δv/t; Δv=√(2gh);
But I do not know what time should I use.
The Attempt at a Solution
I was thinking of using 0,1 second for the time, but I am really not sure if that would be correct. I know this is a simplification of a complex model (it probably vibrates and the rider probably bounces a bit).
Do you think this is a good way of calculating the force? Do you have any other suggestions?
Please help me.
Thank you, Vid
