Torque HELP!
The drawing shows an A-shaped ladder. Both sides of the ladder are equal in length. This ladder is standing on a frictionless horizontal surface, and only the crossbar (which has a negligible mass) of the "A" keeps the ladder from collapsing. The ladder is uniform and has a mass of 12.0 kg. Determine the tension in the crossbar of the ladder.
This is what I did:
I took gravity and multiplied by 1.00 m and then multiplied by cos 75. I didvided this value by 4.00m*sin 75...I'm completely wrong help!
[(9.8)(1)(cos 75)]/[(4)(sin75)
The picture is attached***
