Consider a Li/Li conducting electrolyte/Li symmetric cell. The two electrodes are identical. Drawequivalent circuit of the full cell. Use following parameters to make the Nyquist plot of 1) a single Li /Lielectrode without electrolyte. 2) The full cellwith both electrodes and electrolyte. Choose frequency range of 10kHz to 1 Hz. In each case, determine the characteristic frequency corresponding to the top of the semicircle. Are they the same

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.

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

The higher the astm grain size number, the finer the gran is. a)-true b)-false
