Two sources of sound S1 and S2 vibrate at same frequency and are in ph

1.	Two sources of sound S1 and S2 vibrate at same frequency and are in phase (figure 16-E8). The intensity of sound detected at a point P as shown in the figure is I0. (a) If θ equals 45∘, what will be the intensity of sound detected at this point if one of the sources is switched off? (b) What will be the answer of the previous part if θ=60∘?
Answer» Two sources of sound $S_{1}$ and $S_{2}$ vibrate at same frequency and are in phase (figure 16-E8). The intensity of sound detected at a point P as shown in the figure is $I_{0}$ . (a) If $θ$ equals $45^{\circ}$ , what will be the intensity of sound detected at this point if one of the sources is switched off? (b) What will be the answer of the previous part if $θ = 60^{\circ}$ ?

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
