Design sequential circuit with two JK flip-flops A and B and two inputs E and x. If E = 0 the circuit remains in the same state regardless of the value of x. When Ex = 11; the circuit goes through the transitions from 00 → 01→ 10 → 11 → 00, and repeat. When Ex = 10, the circuit goes through the state transitions from 00 → 11 → 10 → 01 → 00, and repeat. 

Consider an SDOF system of mass m, stiffness k, and damping coefficient c. Now if the mass of the system increases 4 times, what will be the change in the damping ratio?

no changes

become half

increases by 2 times

increases by 4 times

Suppose you have to design a box in that has an expensive product in it, if the mass of the item 100 gm, there is some stuffing material in this box which providing some kind of flexibility to this item that is inside say 10N/m. Now if the box is lifted 3m above the ground to carry it from one place to another then what is the vertical dimension of the box

160 cm

165 cm

170 cm

175 cm

An oil storage tank has 20mm steel walls covered with 50mm of fiber glass insulation. if the oil temperature is kept at 150 degree Celsius, what is the rate of heat loss when the outside temperature is 20 degree Celsius and external air coefficient is 20W/m². How much would the heat loss be reduced by doubling the thickness of the insulation?

3. Find the angle of the largest right circular cone which can be inscribed in a sphere of

radius 9 inches.

4. A statue 10 feet high is standing on a base 13 feet high. If an observer’s eye is 5 feet

above the ground, how far should he stand from the base in order that the angle

between his lines of sight to the top and bottom of the statue is a maximum. (How far

should he stand to get the best view of the statue.

5. A steel girder 27 feet long is to be moved on rollers along a passageway 8 feet in

width and into a corridor at right angles to the passageway. If the horizontal width of

the girder is neglected, how wide must the corridor be in order that the girder can go

around the corner?
