Tutorial 1 (Force Vector)

KE26303 APPLIED MECHANICS Tutorial 1 (Force Vector) 1. Determine the magnitude of the resultant force acting on the screw eye and its direction measured clockwise from x axis. (Problem 2-1) 2. Determine the magnitude and direction of the component force F1. Express the result in terms of the magnitude s of the component F2 and resultant FR and the angle . (Problem 2-25). 3. Determine the magnitude of the resultant force and its direction, measured clockwise from the positive x axis. (Problem 2-32). 4. Determine the magnitude of the resultant force and its direction, measured counterclockwise from the positive x axis. (Problem 241). 5. Specify the magnitude F3 and directions 3, 3 and 3 of F3 so that the force of the three forces is FR = {9j} kN. (Problem 2-72). 6. Determine the length of the crankshaft AB by first formulating a Cartesian position vector from A to B and then determining its magnitude. (Problem 286) 7. Determine the lengths of wires AD, BD and CD. The ring at D is midway between A and B. (Problem 2-87). 8. The guy wires are used to support the distribution pole. Represent the force in each wire in Cartesian vector form. Neglect the diameter of the pole. (Problem 2-100) 9. Determine the angle  between the two cords. (Problem 2-119) 10. A man raises a 10 kg joist, of length 4 m, by pulling on a rope. Find the tension in the rope and the reaction at A.
