$($DO NOT CHANGE UNITS$)$

For the beam shown in Figure II:

Tick Boxes to check that you solved all auestions

$1-$ Compute the reactions at the supports A and C$.($CHECK MORE THAN ONE TIME BEFORE YOU CONTINUE$).(8$ points$)$

$2-$ Using sections, compute the shear force and bending moment at points B and D $($take advantage of the results obtained here as you draw diagrams in question $4).(6$ points$)$

$3-$ Using "convenient" origin$($s$),$ write the equations for shear force and bending moment in the whole beam, but DO NOT draw the diagrams $($yet$).(12$ points$)$

$4-$ Using the method of integration $($or areas$),$ draw the shear and moment diagrams $($use the space provided below for the diagrams and draw neatly and to scale as much as you can$).$ Show the important and necessary features and values on the diagrams. $(24$ points$)$
