Design a counter with two jk flip-flops (a and b) and an input (x) that counts 0 1 2 3 0 … when x = 0 and counts 0 1 2 0 … when x = 1. design this assuming that x is never 1 when the count is 3. show the minimum equations for each.

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.
