Consider the circuit below. Assume the switch has been in its initial position for a long time, and it switches position as indicated at t = 0. a. Find v(t) for all t > 0.
b. Sketch v(t) as voltage vs. time; annotate critical values on your sketch (see video lectures for example).
c. How much energy is stored in the capacitor at t = 0?

Fluids at rest possess no flow energy. a)- true b)- false

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.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.
