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

29.
The resultant force of a wind loading acts perpendicular to the face of the sign as shown. Replace this force by an equivalent force and couple moment acting at point O.
Â
A. | F = -120i lb, M = (-3000j+1800k) lb-ft |
B. | F = -120i lb, M = 3500i lb-ft |
C. | F = -120i lb, M = -3500j lb-ft |
D. | F = -120i lb, M = 3500k lb-ft |
