1. If the point A = (ax, ay, az) and point B = (bx, by, bz) in Cartesian form, then the force F which acts at A towards B can be found by Student Response False General Feedback: The position vector = to - from. So here you'd have point B - point A. Score: 5/5 2. Calculate the reaction loads at the floor. Give your answers with three significant digits using positive numbers. (Hint: if you get a negative number for your answer, it's positive in the other direction.) Units should be in forms such as in, ft, in lb, kN, N, kN m, or ft lb. Use no periods or dashes in your units. reaction in horizontal = 1.----- in units of 2.-----, right or left? 3.----- reaction in vertical = 4.----- in units of 5.-----, up or down? 6.----- reaction moment = 7.----- in units of 8.-----, CW or CCW? 9.-----
