Hi all,
I am trying to calculate a value for stress in a right angled bracket. this would be simple for me if the load was a static load, it would cause the bracket to bend around a point etc so i can get moments to find its bending stress.
however this bracket will be stopping a moving cart, to act as a mechanical stop.
The cart travels towards the bracket, it has a mass and an acceleration. on impact, how can the stress in the bracket be derived.
on first thoughts, i would try Castigliano's method for strain energy. Am i right in thinking this?
any pointers on what methods to look into would be great.
