Two vertical wires are suspended at a distance of 500 mm apart as shown in Fig. 4.18. Their upper ends are firmly secured and their lower ends support a rigid horizontal bar, which carries a load of 200 N. The left hand wire has a diameter of 1.6 mm and is made of copper, and the right hand wire has a diameter of 0.9 mm and is made of steel. Both wires, initially, are 4.5 metres long. Determine: (a) Position of the line of action of the load, if both the wires extend by the same amount. (b) Slope of the rigid wire, if the load is hung at the centre of the bar. Neglect weight of the bar. Take E for copper as 100 GPa and E for steel as 200 GPa. [Ans. 170 mm; 0.15]

Question
Transcribed Image Text:4. Two vertical wires are suspended at a distance of 500 mm apart as shown in Fig. 4.18. Their
upper ends are firmly secured and their lower ends support a rigid horizontal bar, which carries
a load of 200 N. The left hand wire has a diameter of 1.6 mm and is made of copper, and the
right hand wire has a diameter of 0.9 mm and is made of steel. Both wires, initially, are 4.5
metres long. Determine:
(a) Position of the line of action of the load, if both the wires extend by the same amount.
(b) Slope of the rigid wire, if the load is hung at the centre of the bar. Neglect weight of the bar.
Take E for copper as 100 GPa and E for steel as 200 GPa.
