Example 6-1 I

B

~FB = 500~i (4)~FBA = FBA~j (5)~FBC = FBCcos45

~i + FBC sin45~j (6)

~FRB = ~FB + ~FBA + ~FBC = 0 (7)

FBCcos45 + 500 = 0 (8)

FBC sin45 + FBA = 0 (9)

Example 6-1 II

C

~FC = FC~j (10)~FCA = FCA~i (11)~FCB = FCBcos45

~i + FCBsin45~j (12)

~FRC = ~FC + ~FCA + ~FCB = 0 (13)

FCBcos45 + FCA = 0 (14)

FCBsin45 + FC = 0 (15)

Example 6-1 III

A

~FA = FAx~i + FAy~j (16)

~FAB = FAB~j (17)~FAC = FAC~i (18)~FRA = ~FA + ~FAB + ~FAC = 0 (19)

FAx + FAC = 0 (20)

FAy + FAB = 0 (21)
