Slider block B moves to the right with a constant velocity of 300 mm/s.

Determine

(a) the velocity of slider block A,

(b) the velocity of portion C of the cable,

(c) the velocity of portion D of the cable,

(d) the relative velocity of portion C of the cable with respect to slider block 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.
