Give answer in rectangular coordinates. Determine the magnitude and the direction of the smallest force P for which this system can be replaced with a single force at E .(a) the tension in AD, (b) the magnitude and direction of the resultant of the two forces. 6. A rigid pole and cross-arm assembly is shown here. Express T as a vector. Determine the vector expression for the moment of the 1.2-kN tension (a) about point O and (b) about the pole z-axis. Find each moment in two different ways. Does it make any ...
2—and then this resultant is added to the third force, yielding the resultant of all three forces; i.e., R = (FF 1 + F 2) + F 3. Using the parallelogram law to add more than two forces, as shown here, often requires extensive geometric and trigonometric calculation to determine the numerical values for the magnitude and direction of the ... The Moment of a couple, M is computed as the product of the force (F) times the perpendicular distance (d) between the two equal and opposite forces Example: Determine the Moment at A, and at B (Assume Moment is positive for counterclockwise rotation) Mcouple= F x d F F d
