1.Computations are to be made for a street curve with delfection angle delta = 50 degrees 00 minutes 00 seconds and centerline radius of 120 feet. The PI is at station 8+72.43. Calculate the deflection angles and chords to stations 8+25, 8+50, 8+75, 9+00 and 9+21.19
2.IF the bulk density of coarse grained soil is 1760 kg/m^3 what is its void ratio, e, and saturation, S? Draw the complete phase body diagram and show the masses and volumes.
3.Knowing that each of the shafts AB, BC, and CD consists of a solid circular rod, determine (a) the shaft in which the maximum shearing stress occurs, (b) the magnitude of that stress.
