It may sound like a silly question but I really need some help. Not with the maths, I know that's beyond me I'll plug the numbers into an online calculator when I know what it is is I should be doing and that's where I need you.
The set up:
A random length of 25mm square tube with a wall thickness of 1.5mm is held rigid at one end.
The question:
At what point along the piece of square tube will the average person weighing 70kg, be able to stand before the bar bends to the point of plastic deformation?
Do I have to specify a length to find out the moment of turning force in Newtons and then see if this is with the parameters of the material, or can I do a dircect calculation using the 70kg weight?
What stats do I need about the material (plastic modulus, inertia etc) and how do these stats relate to the question?
For your info I've stood on the length of tube and it's around 650mm
