A horizontal curve is being designed through mountainous terrain for a four-lane road with lanes are 10 ft wide. The central angle (Δ) is 40°, the tangent distance is 520 ft, and the stationing of the PI is 2600+00. The coefficient of friction is .08 and the curve’s superelevation is .09 ft/ft. What is the stationing of the PC and PT, and what is the safe vehicle speed?

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
