A uniform lever of mass 4.1 kg and length 4 m is being suspended horizontally from the ceiling by means of two strings attached to the
ends of the lever. The string attached to the right end
makes an angle of 40 ° with the horizontal-left on the ceiling.
The string attached to the left end makes an angle of 35 °
with the horizontal-right on the ceiling. An object of
mass 15.1 kg is hanging from the lever 0.5 m away from the right end. Calculate the tension of the string attached to the right and the left end?

I know the formula..Im confused on  what length you use for. I multipled 4m 9.8 sin40 equal to -4.1 (9.8)(1.5)-(15.1)(9.8)(0.5) for T1 but not correct!
