Aspherical tank of radius 1 m containing radioactive material is buried in the earth. the distance between the earth's surface and the tank center is 4 m. heat release due to radioactive decay in the tank is 500 w. calculate the steady temperature of the tank's surface if the earth's surface is at 20°c and the thermal conductivity of the earth at this location is k 1.0w(m k)

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

What precautions should you take to prevent injuries when dealing with heavy loads?

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.
