Two steel wires support a moveable overhead camera weighing W = 25 lb (see figure) used for close-up viewing of field action at sporting events. At some instant, wire 1 is at on angle α = 20° to the horizontal and wire 2 is at an angle β = 48°. Both wires have a diameter of 30 mils. (Wire diameters are often expressed in mils; one mil equals 0.001 in.)
Determine the tensile stresses σ1 and σ2 in the two wires.
