1.	A uniform wooden stick of mass 1.6 kg of length l rests in an inclined manner on a smooth, vertical wall of height h(<l) such that a small portion of the stick extends beyond the wall. The reaction force of the wall on the stick is perpendicular to the stick. The stick makes an angle of 30∘ with the wall and the bottom of the stick is on a rough floor. The ratio hl and the frictional force f at the bottom of the stick are (g=10 ms−2). Also, the normal reactions at the two points of contact on the stick are equal.
Answer» A uniform wooden stick of mass 1.6 kg of length $l$ rests in an inclined manner on a smooth, vertical wall of height $h (< l)$ such that a small portion of the stick extends beyond the wall. The reaction force of the wall on the stick is perpendicular to the stick. The stick makes an angle of $30^{\circ}$ with the wall and the bottom of the stick is on a rough floor. The ratio $\frac{h}{l}$ and the frictional force $f$ at the bottom of the stick are $(g = 10 m s^{- 2})$ . Also, the normal reactions at the two points of contact on the stick are equal.

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
