A street lamp weighs 158 n. it is supported equally by two wires that form an angle of 104⦠with each other. what is the tension of each of these wires?

Respuesta :

The tension in both the wires will be split equally. By drawing a sketch and developing the resultant arrows, angle formed by each wire with the ground will be 38 degrees. If T is the tension in each wire, then T = (158 / 2) / sin (38) = 128.32 N
