An AB copper bar is positioned at room temperature with a gap S of 0.0002m between the A end and a rigid constraint (see figure). The bar is supported at the B end by an elastic spring with elastic constant k= 210x10^6 N/m. Calculate the compressive stress on the bar if the temperature only on the bar increases by 27°C. (For copper, use σ = 17.5x10^-6/°C and E = 110 GPa). Despise the action of gravity
