A rectangular sign over a store has a weight of 340lb, with the center of gravity in the center of the rectangle. The support against the wall at point C may be treated as a ball-and-socket joint. At corner D support is provided in the y-direction only. Calculate the tensions T 1and T 2
in the supporting wires, the magnitude of theitotal force supported at C, and the lateral force R supported at D. The force R is positiveif it points in the +y-direction, and negative if it points in the - y-direction
a) T₁ = 1b
b). T₂= 1b
c) C= 1b
d). R= bb
