Consider a hot working operation where there is no work hardening but the flow stress is sensitive to strain rate. Calculate the maximum strain rate that can be used in the deformation if the flow stress cannot exceed 200 MPa. Assume a strain rate sensitivity exponent is 0.1 and the strength constant is 175 MPa. There is no effect of friction with the tooling

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.

What are the two (02) benefits, which may result from a successful implementation of preventive maintenance (pm) program in an organization? (clo3)a)- lean manufacturing b)-overlapping responsibilities c)-the planner is not qualified d)-accurate contractor information e)-reduction in equipment redundancies f)-accurate stores information

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