Consider the bram shown in (Figure 1). Figure 3 m 6 m 12 kN/m B 1 of 1 Part B Draw the moment diagram for the beam. Follow the sign convention. Review Click on "add vertical line off" to add discontinuity lines. Then click on "add segment" button to add functions between the lines. Note 1 - Draw a vertical line to denote local maximum or minimum. Note 2 - 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 3 - 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 correct visually because the lines overlap, but the system will mark it wrong. 十血 12 kN/m 3 m C 6 m M (kN·m) No elements selected 50 40 30 20 10 gi ✓ 0+ 0 1 2 3 4 5 6 -10+ -20 -30 -40 -50 Add discontinuity lines and select segments to add to the canvas.

Review Click on "add vertical line off" to add discontinuity lines. Then click on "add segment" button to add functions between the lines. Note 1 - You should not draw an "extra" discontinuity line at the point where the curve passes the x-axis. Note 2 - 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 3 - 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. Use the button "change segment" if necessary. Note 4 - 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 correct visually because the lines overlap, but the system will mark it wrong. 血 A 3 m 12 kN/m C 6 m No elements selected V (kN) 40 20- 0+ 0 B 6 -20- -40 B x (m)
