During a steady right turn, a person exerts the forces shown on the steering wheel. Note that each force consists of a tangential component and a radially-inward component. Determine the moment exerted about the steering column at O. The moment will be positive if counterclockwise, negative if clockwise. 39 9.5 N 16 A 405 mm 9.5 N 39 Answer: Mi B 16 N-m The flanged steel cantilever beam with riveted bracket is subjected to the couple and two forces shown, and their effect on the design of the attachment at A must be determined. Replace the two forces and couple by an equivalent couple M and resultant R at A. The couple is positive if counterclockwise, negative if clockwise. A Answers: 1.80 kN 0.54 m 1.47 m 63 0.12 m 0.12 m 690 N-m L--x 1.05 kN M = i kN-m R-i i+ i j) kN Replace the three forces shown by an equivalent force-couple system at point A. If the forces are replaced by a single resultant force, determine the distance d below point A to its line of action. 120 N 580 mm 580 mm 170 N 580 mm 235 N Answers: Force-couple system at A. The force is positive if to the right, and the couple is positive if counterclockwise. R = i M = i Single resultant force. N N-m d = i mm
