+Z 3 m 3 m 1m 4 m 2 m 3 m 2 m 200 N +X

A 200 N bucket and a 60 N external load are supported

by 3 ropes as shown, and the system is in equilibrium (not

moving). (a) Determine the unit vectors uDA, uDB and uDC,

respectively.

(b) Calculate the magnitude of the forces FDA, FDB and FDC

for

the system to stay in equilibrium.

(Hint: Sum forces at point D, ∑ Fx =0, ∑ Fy =0 and ∑ Fz
