Unformatted text preview: M= X*Fy – Y*Fx. Show units! C) (5 points) Find the net moment (sum of the moments of all three forces). Show units! Problem 2. (5 points) Show all work. Consider the truss. External force P is applied at point D. A) (5 points) Draw the free body diagram for the truss. Problem 3. (5 points) Show all work. What angle (marked as θ) does the resultant force of F 1 and F 2 make with the x-axis? Hints: 1) Express F 2 in terms of unit vectors i and j . 2) Find the resultant force vector in terms of unit vectors i and j. Now you can easily find the angle....
