The one-dimensional slab below has constant properties and no internal heat generation. the slab is initially at a uniform temperature ti. an electrical heater at the bottom surface is energized for t> 0, providing a uniform heat flux at the surface x=0. all boundaries are perfectly insulated. a) simplify the heat conduction equation and provide the necessary boundary conditions and initial condition. b) on t-x coordinates, sketch the temperature distributions for the initial condition and for three times after the heater is energized. will a steady-state temperature distribution ever be reached? c) sketch the flux versus time for planes x=0, x=l/2, and x=l.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
