ok ... its making a little sense, so where do you go from here ...

i wish i could get to the answers but i have no idea how to do this problem, that's y i posted the Q here, so i guess ill have to go step by step with u

Torque H = RFcos theta Torque V = RFsin theta Torque mass = RF ^^ do these equations make sense?

the torque of the mass is mg(d) t = 4(9.8)(d) << so what's d .. am i on right track, somewhat?

sprry but the reason i am a little fristaretd and in a hurry is because i have this class in exactly one hour and this is my last Q of the homework, and the instructor is very strict about homeworks

torque = T distance sin 30 is the distance 2? and is it sin 30? i think i get the picture, its like Newtons 2nd law, so you find the torque of the mass and then subtract the torgue of H and v

clock wise as positve, meaning mg of the 4kg block would b positive

well i tried many things but right now i just did: Torgue 1 + torque 2 = torque 3 4(4 x 9.8) [from the mass of 4 kg]+ 2 (2 x 9.8) [the beam] = 2 T [tension], so i got T = 98 N i am really confused because net torque = I angular acceleration and isn't net torque suposed to b zero since the...

here is the Q i just cannot solve, i have tried sooo much: I tried my best to make the figure from paint, so please help. http://img207.imageshack.us/img207/6315/phyhv3.jpg Find the forces T,V, and H for the system in equilibrium shown above. Note the beam is homogeneous, uniform, 4 meters...
