A plane wall of a furnace is fabricated from plain carbon steel (k = 60 W/m middot K, p = 7850 kg/m3, c = 430 J/kg middot K) and is of thickness L = 10 mm. To protect it from the corrosive effects of the furnace combustion gases, one surface of the wall is coated with a thin ceramic film that, for a unit surface area, has a thermal resistance of R t,f = 0. 01 m2 K/W. The opposite surface is well insulated from the surroundings

a quality control engineer is testing the battery life of a new smartphone. the company is advertising that the battery lasts 24 hours on a full-charge, but the engineer suspects that the battery life is actually less than that. they take a random sample of 50 of these phones to see if their average battery life is significantly less than 24 hours.

q8: (gearing) (15%) when a motor (with motor rotator inertia jm) is driving a load (with inertia jl) through a gearhead with a gear ratio r. (a) to maximize the acceleration of the load, what gear ratio, r, should we use? (b) to maximize the acceleration of the motor shaft itself, what gear ratio, r, should we use? larger, equal or less than the answer provided in (a)? (c) to minimize the power going into the motor inertia, what gear ratio, r, should we use? larger, equal or less than the answer provided in (a)?

A program repeatedly performs a three-step process: It reads in a 4KB block of data from disk, does some processing on that data, and then writes out the result as another 4KB block elsewhere on the disk. Each block is contiguous and randomly located on a single track on the disk. The disk drive rotates at 7200RPM, has an average seek time of 8ms, and has a transfer rate of 20MB/sec. The controller overhead is 2ms. No other program is using the disk or processor, and there is no overlapping of disk operation with processing. The processing step takes 20 million clock cycles, and the clock rate is 400MHz. What is the overall time needed to process the 4KB block assuming no other overhead?
