A 3% grade meets a 6% grade at an elevation of 524.91 ft. For a passing sight distance of 2,000 ft, find the minimum length of the vertical curve that allows for passing using the minimum curve length equations. Also, calculate the elevation of the middle point of the curve.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Find the minimum film thickness for a journal bearing with the data below. shaft diameter, d-50 mm, clearance ratio, cdratio? 0.001, shaft speed, n 2000 rpm; bearing length. i 200 mm; eccentricity ration, ? -0.55. ( note, cdratio-ca/d) the minimum film thickness is um

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
