A loudspeaker of mass 24.0 kg is suspended..?

A loudspeaker of mass 24.0 kg is suspended a distance of h = 1.60 m below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 4.00 m 

What is the tension T in each of the cables?

Use 9.80 m/s2 for the magnitude of the free-fall acceleration.

    T1 = T2 = m*g/(2*h/l) = 24*9.8/(2*0.4) =24*9.8*1.25 = 294 N

    Θ = arcsin(1.6/4) = 23.6°

    2*T*sin23.6 = 24*9.8 = 235.2N

    T = 235.2/(2*sin23.6) = 294N <<<<<
