$(5)$

The propped cantilever beam shown is subjected to a uniformly

distributed load of $w=15\mathrm{.}00k\frac{N}{m}$ over a portion of its span.

Determine the magnitude of the reaction force acting at $B($in kN $).$

Assume EI is constant for the beam. Hint: The reaction force is

greater than $30\mathrm{.}00$ kN and less than $44\mathrm{.}00$ kN $.$
