10.38 A direct-coupled amplifier has a low-frequency gainof 40 dB, poles at 1 MHz and 10 MHz, a zero on the negativereal axis at 100 MHz, and another zero at infinite frequency. Express the amplifier gain function in the form of Eqs.(10.56) and (10.57), and sketch a Bode plot for the gainmagnitude. Does this amplifier have a dominant pole? If so, at what frequency? What do you estimate the 3-dB frequencyto be?

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
