A 54.0 kg person takes a nap in a (lightweight) backyard hammock. Both ropes supporting the hammock are at an angle of 16.9° above the horizontal. Find the tension in the ropes.

M*g = 54 * 9.8 = 529.2 N. = Wt. of the person.
Eq1: T1*Cos16.9 = -T2*Cos(180-16.9).
0.957T1 = 0.957T2.
T1 = T2.
Eq2: T1*sin16.9 + T2*sin(180-16.9) = -529.2[270o].
0.291T1 + 0.291T2 = 529.2.
Replace T1 with T2:
0.291T2 + 0.291T2 = 529.2
0.581T2 = 529.2
T2 = 910 N. = T1.
