Summarize how the engineering team in the following scenario practiced green construction methods. A team of engineers designed a new school to use solar heat as its primary heat source. The school is built from materials recycled from an old high school, and uses wastewater for its grounds.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

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.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
