1. A horizontal curve with a radius of 800ft connects the tangents of a two-lane highway with a design superelevation of 0.06 and a coefficient of side friction of 0.14. Lanes are to be 12-feet wide and there is no median. Please calculate: a) What is the speed limit to be posted for a vehicle traversing this curve

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
