A mild steel wire of length 2L is strethched, within its elastic limit horizontally between two pillars(figure). A mass of m is suspended form the midpont of the wire. Strain in the wire is

A mild steel wire of length 2L and cross-sectional area A is stretched, well within elastic limit, horizontally between two pilars show in the figure A mass m is suspended from the mid point of the wire. Strain in the wire is .

A mild steel wire of length 1.0m and cross sectional area 5.0xx10^(-2)cm^(2) is stretched, within its elastic limit horizontally between two pillars. A mass of 100g is suspended form the midpont of the wire. Calculate the depression at the midpoint (Y_("steel) = 200GPa)

A mild steel wire of length 2L and crosssectional area A is stretched, well within elastic limit, horizontally between two pillars as shown in figure. A mass m is suspended from the mid point of the wire, the mid point lower by distance x. Then strain in the wire is ......

A mild steel wire of length 2L and cross sectional area A is stretched, well within elastic limit, horizontally between two pillars. A mass m is suspended from the mid point of the wire. The mid point is lowered by x. Strain in the wire is
