A new road is to be constructed to connect two existing roads. The centerline intersection with the west road (station 0 00) is at an elevation of 29.68 ft; and intersection with the east road (station 6 73) has an elevation of 34.25 ft. The centerline has a uniform grade between the two intersections. A stake has been set at each station at an arbitrary elevation. The surveyor needs to label the stakes with cut/fill amounts and prepare a grade sheet. a. Complete the grade sheet showing the cuts and fills b. At which station is the line of no cut/no fill

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
