HW: 2-1-4 Using the parallelogram law, graphically find the magnitude of the resultant of F, and F knowing that F, 250N and F2 175N. Use the scale 1 50N. Use the squares between the filled in circles in the figure to determine the directions of the forces. Hint: See video 2-04. Answer(s): 2 Force magnitudes are not drawn to scale.
HW: 2-1-8 Using the parallelogram law, graphically find the smallest F, if the resultant is horizontal with a magnitude of 1000lb. Also find F2. Use the scale 1in- 250b. Hint: See video 2-10. You may want to also do Hw 2-1-7 to see the major difference with just a slight change in wording. Also see video 2-04 Answer(s): 45° 2
HW: 2-1-12 Using the parallelogram law, trigonmetrically find the magnitude of the resultant of F, and F2 knowing that F1-250N and F2-175% Use the squares in the figure to determine the directions of the forces. Example, ø- tan1 (rise/run) Answer(s): 2 Force magnitudes are not drawn to scale.
