A horizontal curve was designed for a four-lane highway for adequate SSD. Lane widths are 12 feet, and the superelevation is 0.06 and was set assuming maximum fx. If the necessary sight distance required 52 feet of lateral clearance from the roadway centerline, what design speed was used for the curve? Answer in mi/hr.
A gas is compressed at a constant pressure of 0.800 atm from 9.00L tp 2.00L. in the process, 400J of energy leave the gas by heat. (a) What is the work done on the gas? (b) What is the change in it internal energy?
For energy conservation, materials with a high thermal capacity are effective in climates in which the heat flow through the building envelope is:
The rigid bar abcd is supported by a pin at B and restrained by identical steel bars at C and D, each of area 250mm 2 . if the temperature is increased by 8 0 C, find out the force P that will cause the bar at c to be stress-free.
