Question $3/$ Vraag $3$

The A$992$ steel rod is subjected to the loading shown. If the cross$-$sectional area of the rod is $60m{m}^2,$ determine the displacement of B and A$.$ Neglect the size of the couplings at $B,C,$ and $D.$

Die A$992$ stalstaaf word aan die getoonde belasting blootgestel. As die deursnee$-$area van die staaf $60m{m}^2$ is$,$ bepaal die verplasing van $B$ en $A.$ Ignoreer die grootte van die koppelings by B$,$ C$,$ en D$.$
