Two blocks of masses 1 kg and 2 kg are connected by a metal wire going

1.	Two blocks of masses 1 kg and 2 kg are connected by a metal wire going over a smooth pulley as shown in figure. The breaking stress of the metal is (403π)×106 N/m2. If g=10 ms−2, then what should be the minimum radius of the wire used if it is not to break?
Answer» Two blocks of masses 1 kg and 2 kg are connected by a metal wire going over a smooth pulley as shown in figure. The breaking stress of the metal is $(\frac{40}{3 π}) \times 10^{6} N / m^{2}$ . If $g = 10 m s^{- 2}$ , then what should be the minimum radius of the wire used if it is not to break?

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
