Ahorizontal curve on a two-lane highway (10-ft lanes) is designed for 50 mi/h with a 6% superelevation. the central angle of the curve is 35 degrees and the pi is at station 482 + 72. what is the station of the ptand how many feet have to be cleared from the lane's shoulder edge to provide adequate stopping sight distance?

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk
