Along, hollow cylinder. a= 0 the boundaries at r=a and r=b are kept insulated. obtain an expression for temperature distribution t(r, 1) in the solid for times t> 0.

Fluids at rest possess no flow energy. a)- true b)- false

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?
