Multiple Choice Questions 1. The pole supports a 22-lb traffic light. Using Cartesian vectors, determine the moment of the weight of the traffic light about the base of the pole at A. A) MA = (- 132i + 229j) Ib-ft B) MA = (- 132i - 229j – 216k) Ib-ft C) MA = 216k Ib-ft D) MA = (- 229i + 132j) Ib-ft 2. Determine the magnitude and direction of the couple moment. 120 lb 6t 120 lb A) M = 3120 lb - ft CW B) M = 2496 Ib - ft CW C) M = 3900 lb ft CW D) M = 2496 Ib · ft CCW %3!
