Three spur gears transmit power from a motor shaft to a machine shaft in a given geometric arrangement. The middle gear acts as an idler and is supported by two bearings. Find: (a) Determine the radial load on idler shaft bearings for a given direction of motor shaft rotation. (b) Determine the radial load on the bearings for the motor shaft rotation opposite to (a). (c) Give an explanation as to why answers to (a) and (b) are different. (d) Compute a

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.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
