$2($contd$.)$

Find the vertical reaction forces at the supports.

$(20$ marks$)$

Draw the shear force diagram $($SFD$)$ labelling it with your

calculated values at all of the key points.

Using the SFD$,$ determine the location of the point of maximum

sagging bending moment. Determine the value of the bending

moment at this point.

Draw the bending moment diagram labelling it with your

calculated values at all of the key points.
