Question $4$

For the cantilever beam shown below the support reactions at A are;

$A_x=0kN,A_v=15kN(upwards)A_m=44\mathrm{.}25kNm(anticlockwise)$

a$)$ Calculate the value of the shear and the moment in the beam either side of the $10$ kN point load and $8$ kNm moment,

using equilibrium and considerations and free body diagrams.

b$)$ Derive the general mathematical expressions for the shear force and bending moment in the beam in the region $)$

$(equivalencyof$ your equations $by$ substituting $in$ numerical values.
