A soil sphere of mass M and radius R is divided into two unequal parts

1.	A soil sphere of mass M and radius R is divided into two unequal parts. The first part has a mass of 7M8 and is converted into a uniform disc of radius 2R. The second part is converted into a uniform solid sphere. Let I1 be the moment of inertia of disc about its axis and I2 is moment of inertia of new sphere about its axis. The ratio I1I2 is given by
Answer» A soil sphere of mass $M$ and radius $R$ is divided into two unequal parts. The first part has a mass of $\frac{7 M}{8}$ and is converted into a uniform disc of radius $2 R .$ The second part is converted into a uniform solid sphere. Let $I_{1}$ be the moment of inertia of disc about its axis and $I_{2}$ is moment of inertia of new sphere about its axis. The ratio $\frac{I_{1}}{I_{2}}$ is given by

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
