Two artifacts in a museum display are hung from vertical walls by very light wires. Wire T1 is horizontal from the left wall and goes to a center weight of 177N and wire T2 is at a 53 degree angle with the right wall heading from right to left downwards towards the center weight of 177N. From the center weight a wire T3 hangs vertically to a 40kg object.

Question

Two artifacts in a museum display are hung from vertical walls by very light wires. Wire T1 is horizontal from the left wall and goes to a center weight of 177N and wire T2 is at a 53 degree angle with the right wall heading from right to left downwards towards the center weight of 177N. From the center weight a wire T3 hangs vertically to a 40kg object.
Find the tension on T1, T2 and T3.
T3 solved but don't know how to calc. T1 and T2.

ok, on T2, T3... Sum horizontal forces=zero T2-T3cos37=0 that is one equation. Second equation is sum of vertical forces is zero.. T3Sin37-177=0
