If a bolt is broken off flush with a surface, and the bolt is large enough in diameter, then you may be able to use a small to turn the bolt by tapping on the outside diameter of the bolt, but in the reverse direction. Select one: a. Piston b. Center punch c. Both A and B d. Neither A nor B

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.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

The proportional limit is always greater than the yield strength for a material. a)-trune b)- false
