A tower used in an electrical substation supports a power line which exerts a horizontal tension of T = 500 lb on each side truss of the tower as shown. Determine the force in members BC, CM, and LM of a side truss and indicate whether the members are in tension or compression.

CM = 581 lb T, CB = 2050 lb C, LM = 2000 lb T

CM = 833 lb T, CB = 3330 lb C, LM = 2670 lb T

CM = 325 lb T, CB = 3040 lb C, LM = 2670 lb T

CM = 58 lb T, CB = 1646 lb C, LM = 1600 lb T
