NEED IN RUSH! A transmission tower is held in place by bolts at B, C, and D. If the force on the cable AD is 664 N, what is the angle of orientation with respect to the x-axis and y-axis of the wire in bolt D (θD.x and θD.y)? (degrees) Given: y = 20 m XB = XD = 2.4 m ; Xc = 8.3ZB = 4.2 m ; ZC = 2.3 m ; ZD = 10.2 m

Answer true or false in response to the following questions: (a) A force has zero moment about any point along its line of action. (b) A force has no moment about a line parallel to its line of action. (c) The magnitude of the moment of a force about a line equals the product of the component of the force perpendicular to the line and the distance between this component and the line. (d) The moment about a point P of the sum of a set of concurrent forces, placed at the point of concurrency (point P), equals the sum of the moments about P of the separate forces. (e) A couple has the same moment about any point. (f) If we know the moment of a couple about a point A, then we can find the moment of the couple about a specified line BC even if A does not lie on BC. (g) Two force and couple systems are equipollent if they have either the same resul- tant force or if the moments about some point P are the same for both systems. (h) It is possible for a system consisting of a single couple to…
