1.Calculate all parameters and elevations at all even stations for vertical curve that has to passes through fixed point if PVI station is 8+00 and elevations is 5180.2. Fixed point station is 10+00 and elevation 5191.00, g1 = -6.6%, g2 = +5.4
2.For an element with a stress of 50 psi on the horizontal plane, 120 psi on the vertical plane, and 10 psi of shear stress that acts in the positive direction on the vertical plane and negative sense on the horizontal plane; draw the element below with correct orientation and senses. Draw the Mohr’s circle and find the principle stresses
