Question $\frac{2}{?}$ Vraag $2[30]$

$[21,6,3]$

The rod ABCD is fixed at A and $D$ and subjected to the loading $P_1=28kN$ and $P_2=12kN$ as shown in Figure $2.$

$2\mathrm{.}1.$ Determine the reaction forces at A and D$.[21]$

$2\mathrm{.}2.$ Determine the displacement of nodes B and C$.[6]$

$2\mathrm{.}3.$ Determine the normal stress in $AB,BC$ and CD$.[3]$

Take E $=200$GPa.

Die stang ABCD is ingeklem by $A$ en $D$ en is ondenverp aan die laste $P_1=28kN$ en $P_2=12kN$ soos getoon in Figuur $2.$

$2\mathrm{.}1.$ Bereken die reaksie kragte by A en D$.[21]$

$2\mathrm{.}2.$ Bereken die verplasing van nodes $B$ en $C.[6]$

$2\mathrm{.}3.$ Bereken die normaalspanning in $AB,BC,$ en CD$.[3]$

Neem E $=200$GPa.
