Question $4.$

$2$kN at A and $4$kN at Abc. Assume that the upward reaction

of the ground is be uniformly

distributed. Derive equations for

the shear force and the bending

moment and draw the shear and

bending$-$moment diagrams for the

beam $AB$ and determine the

maximum value $($a$)$ of the shear,

$($b$)$ of the bending moment.
