Problem 7.87 6 of 6 Review Figure1 of 1 A horizontal beam AB fixed to a vertical wall by its left end A is shown in the figure. A 2 kilonewtons per meter uniform distributed loading acts vertically downward on the 3-meter long segment of AB starting at A. A triangular distributed loading acts vertically downward on the rest of AB. Its 4 kilonewtons per meter peak intensity corresponds to the point which is 1.5 meters to the left of point B. Part A Draw the shear diagram for the beam. Follow the sign convention. (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 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 - 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. No elements selected x(m) V(kN) 0.0 1.5 3.0 4.5 -10 -5 0 5 10 Add discontinuity lines and select segments to add to the canvas. Request Answer Part B Draw the moment diagram for the beam. Follow the sign convention. Click on "add vertical line off" 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.

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.
