I'm going to build a swingset/gym in my 4yr old's bedroom so during the winter he can satisfy his climbing needs without climbing on me
How can I calculate the height (or thickness) of the beam I will need to use to support his weight, and perhaps the weight of a couple of his friends, too?
The beam will be lag bolted into studs in the wall, with an approximate distance of 10 feet between the walls. Assume my sons weight at about 30 lbs, but multiply it by 10 to allow for friends and monkey business.
Would a standard 2x4 stud mounted with the 1-1/2" side parallel to the floor be enough of a height (3-1/2") to support a 300 lb weight at any point along the beam (I think the worst location is directly in the center - the furthest point from each support). Or should I go with a 2x6 plank with the 5-1/2" side as the height?
I would appreciate a physics formula to determine this to convince my wife
