Problem $07\mathrm{.}058-$ A beam with concentrated loads

For the beam and loading shown, $P=9kN.$

Problem $07\mathrm{.}058.$b $-$ Distance between external loads so the maximum absolute value of the bending moment is the smallest

Determine the distance a for which the maximum absolute value of the bending moment in beam $AB$ is as small as possible. $($Round the final answer to three decimal places.$)$

The distance $a$ is m $=9$
