A 20 kg loudspeaker is suspended 2.0 m below the ceiling by two cables that are each 40 degrees from the vertical.?
A kg loudspeaker 20 is suspended 2.0 m below the ceiling by two cables that are each 40 degrees from the vertical. What is the tension in the cables? (In Newtons)
the mass of the speaker = W = weight 20 kg speaker = (20) (9.81) = 196.2 N = tension in each cable (W / 2) / cos 40 = 40 = 128.1 98.1/cos comment YEARS N: a relatively simple problem to solve, but oa diagram / w to explain the solution - it may seem more complicated than it is.
