A horizontal curve is to be designed for a two-lane road in mountainous terrain. The following data are known: Intersection angle: 40 degrees, tangent length = 436.76 ft, station of PI: 2700+10.65, fs = 0.12, e = 0.08. Determine: (a) design speed (b) station of the PC (c) station of the PT (d) deflection angle and chord length to the first 100 ft station

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
