Let’s explore the accuracy of a simple piecewise-linear model:

(a) find the parameters (vd0, rd) of a piecewise-linear model of a diode for which the measured voltage across its terminals vd is 0.7 v when a current of id = 1 ma is flowing. assume vt = 50 mv. the piecewise-linear model is to intersect the measured diode exponential curve at 1 ma and 10 ma.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

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.

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
