Using the circuit topology displayed in fig.7.48(e), arrange to bias the nmos transistor at id =0.5ma with vd midway between cutoff and the beginning of triode operation. the available supplies are ±5v. for the nmos transistor, vt =1.0 v, λ=0,andkn=1ma/v 2.useagate-biasresistor of 10m? . specify rs and rd to two significant digits.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
