. A constant current of 1 ampere is measured flowing into the positive reference terminal of a pair of leads whose voltage we’ll call vp. Calculate the absorbed power at t = 1 s if vp(t) equals (a) +1 V; (b) −1 V; (c) 2 + 5 cos(5t) V; (d) 4e−2t V, (e) Explain the significance of a negative value for absorbed power

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.
