A. An energy source forces a current of 2A through a load for 10s. Suppose 2.3kJ of energy is given off by the load in the form of heat and light. Calculate the voltage drop the load. Assume the current is not time-varying. B. Suppose it requires -30J of energy to move a point charge q from point a to point b." the voltage drop Vab if (a) 4 = 2C and if (b) q = -6C.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

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.
