When I went climbing in Italy I came across a large number on metal steps like the ones in the pictures which follow this overview. I would like to look into the forces acting on the step in normal use and then what would fracture the bar under unusual loading, eg. falling person, multiple people.
Forces Acting on the Step
Mass of the person / people
Force Diagram
M = Turning Force about wall
T = Force at wall
d = Distance to foot on the step
M = The mass of the person in contact with the step
G = gravity
