How can I calculate the stress on a bracket during impact with a moving cart?

AI Thread Summary
To calculate the stress on a right-angled bracket during the impact of a moving cart, it is essential to consider the dynamic load rather than a static one. The impact involves the cart's mass and acceleration, which complicates the stress analysis. Castigliano's method for strain energy is suggested as a potential approach for deriving the stress during impact. Additional resources, such as mechanics of impact tables, can provide further insights into the calculations. Understanding these dynamics is crucial for accurate stress assessment in mechanical stops.

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.

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

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
