pg4-27

Replace the force F, having a magnitude of F = 40 lb and acting at B, by an equivalent force and couple moment at A.

[A].	F = (32i-24k) lb, M = (-120i+96j-160k) lb-ft
[B].	F = (32i-24k) lb, M = 233k lb-ft
[C].	F = (32i-24k) lb, M = -72k lb-ft
[D].	F = (32i-24k) lb, M = (-120i+160j+40k) lb-ft
