Two steel wires support a movable overhead camera weighing W=25lb (see figure) used for close-up viewing of field action at sporting events. At some instant, wire 1 is at an angle a = 20° to the horizontal and wire 2 is at an angle B = 48°. Both wires have a diameter of 30mils.(Wire diameters are often expressed in mils; one mil equals 0.001in.) Determine the tensile stresses o and o, in the two wires.
