A force given by F rightarrow = (-2i + 6j + 3k)kN acts at a point (4,2,2)m. What is the moment of this force about a line running from the points (0,0,3) m ti (0,4,0)m?
The 2.9-kN force F is applied at point A. (a) Compute the moment of F about point O, expressing it both as a scalar (positive if CCW, negative if CW) and as a vector quantity. (b) Determine the coordinates of the points on the x- and y-axes about which the moment of F is zero. 1.7 m, a 3,b 7. AssumexA 1.4 m, yA y, m A (x y a F b ----x, m
Force F, 1 kN, is applied in the negative y-direction at point
B. The magnitudes of the tension in the cables are T(BC) = 707 N
