$[$Help me with the diagram. Sketc$($h$)/($D$)$raw $1,2,3,4]$

$1.$ Structural Beam Diagram

"Draw a horizontal beam divided into four sections with hinge points labeled A$,$ B$,$ C$,$ and D$.$ Apply the following loads:

A point load at B$,$

A distributed load spanning between C and D$,$ and

A moment load at A$.$

Include reaction forces at supports R$\_$A$,$ R$\_$B$,$ and R$\_$C$,$ and label the lengths of each beam section $($e$.$g$.,$ L$\_1,$ L$\_2."$

$2.$ Shear Force Diagram $($SFD$)$

"Create a graph showing the shear force distribution along the beam. Use a horizontal axis to represent the length of the beam and a vertical axis for shear force values. Start at $\backslash ($R$\_$A$\backslash )$ and depict changes in shear force due to the applied loads. Indicate the zero$-$crossing points and label critical values at A$,$ B$,$ C$,$ and D$."$

$3.$ Bending Moment Diagram $($BMD$)$

"Draw a graph to represent the bending moment along the beam. Use the same horizontal axis for beam length and a vertical axis for moment values. Start with zero moments at free ends $($if applicable$)$ and show how moments increase or decrease due to applied loads. Clearly label peak bending moments and points of inflection."

$4.$ Heat Transfer Diagram

"Illustrate a rectangular plate with dimensions $2$m x $1$m on the x$-$y plane. Show the heat flux distribution q$($x$,$y$)=100+50$x$+20$y using a color gradient, with lighter colors for lower heat flux and darker colors for higher heat flux. Add a small rectangle at a specific point to depict the differential surface element dA$=$dxdy$.$ Mark integration limits for x $(0$ to $2)$ and y $(0$ to $1)$ along the respective axes."
