Hi,
I'm building a filming system that uses two parallel cables to support a mobile camera system.
The cable supports need to fail in bending to reduce the load on the cables.
The supports are a mild steel strap, section dimensions 35mm x 5.5mm, distance between cables 200mm.
Can deflection for such a small structure be calculated by treating it as a simply supported beam with a point load at 100mm?
The results I have don't seem to be right, 1.3684mm deflection for cable loading of 500kg total load 1000 kg.
I'll probably have the supports tested in a lab but I want to be in the right ball park. For the system I'm building the maximum loading for some components is 1500kg, I aiming for failure at 300kg, with a safety factor of 5. The cables are rated at 2500kg each.
Thanks for your help.
