$(3)(4)$

The propped cantilever beam shown is subjected to a uniformly

distributed load of $w=14\mathrm{.}00k\frac{N}{m}$ over a portion of its span.

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

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

greater than $15\mathrm{.}33kN$ and less than $23\mathrm{.}92kN.$ The propped cantilever beam shown is subjected to a uniformly

distributed load of $w=13\mathrm{.}00k\frac{N}{m}$ 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 $48\mathrm{.}04kN$ and less than $74\mathrm{.}35kN.$

$90\mathrm{.}00kN$

The propped cantilever beam shown is subjected to a concentrated

load of $P=90\mathrm{.}00kN.$ Determine the magnitude of the reaction force

acting at $A($in kN$).$ Assume EI is constant for the beam. Hint: The

reaction force is greater than $44\mathrm{.}80kN$ and less than $62\mathrm{.}71kN.$
