On the graphs, can you please clarify where to place verticallines as well as which segment should be added. Ty!
Problem 6.42 A beam is shown in the figure below. (Figure 1) Figure A -2 m 5 kN/m B -1 m C -1 m < 1 af 1 D > ▾ Part A No elements selected Draw the shear diagram for the compound beam. Click on "add discontinuity" to add discontinuity lines. Then click on "add segment" button to add functions between the lines. NOTE - You should not draw an "extra" discontinuity line at the point where the shear curve passes the x-axis. Note - Make sure you place only one vertical line at places that require a vertical line. If you inadvertently place two vertical lines at the same place, it will appear visually correct because the lines overlap, but the system will mark It wrong. kN · 4 2 0 -2 -4 -8 0 -8- -10- 2 m 1 5 kN/m B .. 2 D 1m 1m- 3 AD m 6 of 13 Select the elements from the list and add them to the canvas setting the appropriate attributes.

<Chapter 6 Problem 6.42 A beam is shown in the figure below. (Figure 1) Figure 2 m 5 kN/m I. Is -1 m 1 of 1 Part B No elements selected Draw the moment diagram for the compound beam. Click on "add discontinuity to add discontinuity lines. Then click on "add segment" button to add functions between the lines. NOTE 1 - The curve you choose from the drop-down is only a pictorial representation of a real quadratic/cubic curve. The equation of this curve is not mathematically equivalent to the correct answer. Consequently, slopes at discontinuities and intercepts with the x-axis (if any) are not accurate. NOTE 2 - Draw a vertical line (use the "discontinuity line") to denote local maximum/minimum. same place, it will appear Note - Make sure you place only one vertical line at places that require a vertical line.
