Question
100%
The system shown is at rest. Box 2 weighs 61N. Determine all unknowns, neglecting friction in the pulley and the weight of the knot and each string.
How much does box 1 weigh?
How much does box 3 weigh?
I know that
T1cos(θ) = T2cos(θ)
T1sin(θ) + T2sin(θ) = The Weight of Box 2
But how do I find T1 and T2? ( The Hyp's)
