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.

Items are similar to the free issue items, but their access is limited. (clo5) a)-bin stock items free issue b)-bin stock controlled issue c)-critical or insurance spares d)-rebuildable spares e)-consumables

The characteristic roots of a dynamic system are: 1.7920 1.8160 i, -1.7920 1.8160 i, -0.4160 what is the order of this system? what are the settling time and damping ratio of the system?

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa. s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
