Problem 5-57 Translational Equil.- Part 3 - A
A sign outside a hair stylist's shop is suspended by two wires. The force of gravity on the sign has a magnitude of \(55.7\; N.\) If the angles between the wires and the horizontal are as shown in the figure, determine the magnitude of the tensions in the two wires.
[Ans. \(T_1 = 49.9\; N;\) \(T_2 = 40.8 \;N\)]
\(a = 0\)
The acceleration is zero \((a = 0)\).
The condition to be applied is:
(A) \(\sum F = ma\)
(B) \(\sum F = 0\)
(C) \(\sum F_x = 0,\) \(\sum F_y = 0\)
