Question

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 - 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.

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 - 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.
