Q. A vertically hanging steel wire has the following properties. Length=8.75m, Cross-Sectional area= 0.375 cm cubed. Y=2.10x10^11 Pa, B=1.62x10^11 Pa, S= 0.871x10^11 Pa, Proportional Limit=3.27x10^8 Pa, breaking stress=17.4x10^8 Pa.
A mass is hung from the wire, causing it ro reach half its proportional limits. What is this mass?
Find out the magnitude and direction of the displacement
