Explanation / Answer

components of F1

F1(x) = 606.218 lb

F1(y) = 350 lb

components of F2

F2(y) = 480 lb

F2(z) = 360 lb

components of F3

F3(z) = 533.513 lb

F3(y) = 415 lb

F3(x) = -476.068 lb

summations

Fr(x) = 130.15

Fr(y) = 1245 lb

Fr(z) = 893.513 lb

magnitude of Fr = 1537.963 lb

alpha = 85.145 degrees

beta = 35.952 degrees

gama = 54.481 degrees
