Answer» Consider steady-state heat conduction across the thickness in a plane composite wall (as shown in the figure) exposed to convection conditions on both sides. Given : $h_{i} = 20 W / m^{2} K; h_{\circ} = 50 W / m^{2} K; T_{\infty, i} = 20^{\circ} C, T_{\infty, \circ} = - 2^{\circ} C k_{1} = 20 W / m K; k_{2} = 50 W / m K; L_{1} = 0.30 m a n d L_{2} = 0.15 m$ Assuming negligible contact resistance between the wall surfaces, the interface temperature, $T (i n^{\circ} C),$ of the two walls will be

A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
