(Figure 1) Click on "add vertical line off" to add discontinuity lines. Then click on "add segment" button to add functions between the lines. Note - Make sure you place only one vertical line at places that require a vertical line. If you inadvertently place 2 vertical lines at the same place, it will appear correct visually because the lines overlap, but the system will mark it wrong. 4 + D 800 N 600 N 1200 N- m B -1m. 1m 1 m 1 m No elements selected V (N) 1000 500 I (m) 3 -500 -1000 Add discontinuity lines and select segments to add to the canvas.arrow_forwardQ7: The S ft wall shown here stands 27 ft from the building.

Then click on "add segment" button to add functions between the lines. Note 1 - You should not draw an "extra" vertical line at the location of applied moment. Note 2 - Be sure to indicate the correct types of the functions between the lines, e.g. if in your answer the type of a function is "linear increasing slope" for the function that actually has linear decreasing slope, the answer will be graded as incorrect.

Given this information, it doesn't matter what length you use, or what "X" is, but if it helps, just make up numbers, i.e. length of 5" and X of 10lbs. In class we will be using members that are approximately 6" long and weights that are approximately % Ib, although on the weights we can just add more to get the desired effect. Come to class with design in hand prepared to assemble the 3 different trusses to test with loads. A) x (lbs) B) x (lbs) x (lbs) x (Ibs) C) x (Ibs) 2x (Ibs)arrow_forward
