I am determining the max load a steel ladder can hold when placed on a 65 degree angle. the ladder is 12 ft long and is made out of HSS 1x1x1/8in square steel tubing. my idea was to treat it as a simple beam with a single concentrated load at the center "P". then once that was determined, to apply it to a triangle with "P" being the opposite side. id then solve for the hypotenuse which would be the max load straight down when the ladder was placed at the 65 degree angle. Was i correct in going about it in this way or is there a better way to do it? Thanks in advance!
