How much force to lift a beam

harrytos23 · May 27, 2025

Hi there,

I just have question about how much force is needed to lift the beam at point B.

Point A will be the hinge location (rotation allowed but no x and y displacement), Point B is the spot where I want to lift the beam and X would be the overall length of the beam.
Am I missing/not including needed variable to calculate it? Thank you.

Hint: what is the weight or unit weight of the beam and are there any other loads attached to the beam?

Solve by basic statics where Sum F = 0, and Sum M = 0 about point "a".

oh my bad. I will post it in there. Thank you.
The total weight of the beam is 1468 lbs and there's attached 50 lbs weight on point the other end.

Correct me if I'm wrong but F=0, isn't to see the equilibrium of the beam only?

Solving the M = 0 about "a" should give you your answer.
