the question: a board 2 ft long with weight 50 lb is pressed against a wall. what force, applied at 30 degrees, should be applied to keep it horizontal? i'm not sure how to go about this, so i started by converting the weight of 50 lb to 22.67 kg, then getting a force of mass at 2.31 N then i tried using the pythagorean theorem to find the magnitude of applied force, which would be the hypotenuse, but it's not making sense. i get 0.37 using 2.31 N and i get 0.017 using 50 lb. what am i leaving out? does torque play a part?
