The tank of the air compressor is subjected to an internal pressure of 0.63 mpa. if the internal diameter of the tank is 550mm, and the wall thickness is 6mm (a). construct a net mohr's circle depicting the state of stress acting at any point along the length of the 20 marks (b). illustrate the state of stress above on a differential element (infinitesimal cube).

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.

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?
