2.21 Determine the tensions developed in wires CD.CB, and BA and the angle required for equilibrium of the 15-kg cylinder E and the 30-kg cylinder E. Equations of Equilibrium: Applying the equation of equilibrium along the x and y axes to the free-body diagram of joint C shown in Fig. (a). ΣF, = (: Fac cos 8 - Focos 30º = 0 (1) +TEF, = 0; -F sin 8 + Focsin 30 - 15(9.81) = 0 By referring to the free-body diagram of joint B shown in Fig. (b). ΣF = 0; Fu cos 45º - Focos0 (3) +TEF, = 0; Fusin 45° + Fesin -30(9.81) = 0 Solving Eqs (1) through (4). yields F = 395 SN Ans Fco = 323.2 N Ans F = 280.2 N Ans = 2.95 Ans FED FEA 30 to х 450 B Foc 15(9.81) N 30(9.81) N (6) (a)
