- 1. Find the moment of the 500 N force shown about Point A. Write your answer using 2 significant digits. A 200 mm F= 500 N 30° B 250 mmProblem 1 Let A = 3 i - 3j +k and B= -2 i + (-1) j + 5 k. A. What is the cross product C = B x A ? B. What is the dot product C B?Could you provide a diagram and explanation of why the arctan of Ac/At gives the direction of the acceleration vector? I'd like to understand. I'm assuming that the angle is in reference to the axis of the radius. Thank you.
