Using the Tsai-Hill failure criterion, determine the strength of a lamina under equal biaxial tension and shear at 45o to the fiber direction 2 , xy s σσ τ = = that is, determine 0 2,, uu u xy s σ σ τ say F = = = at failure in terms of 12 6 F F and F2.

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.

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
