A load of W = 34 kN is lifted through a boom 'BCD' as shown in the figure. The boom makes an angle of 60 degrees with the vertical. Neglect the weight of the boom for this problem, L1 = L2 = 2.6 m. The pulley at 'D' is frictionless.

 

a.) Determine the angle ‘α’ in degrees.

b.) What is the tension in cable 'AC' in kN?

c.) What is the horizontal component at 'B' in kN?
