Building alu based 4-bit addition using two 74sl74 (4 d ff's) and a 4-bit adder. provide an implementation to perform the following alu addition operation add a. b- this operation adds a and b and stores the result in a create a 4-bit register using 4 d ffs and it acts as an accumulator. this accumulator is connected with an adder and is performing the following task the initial value of the accumulator is 0 and every time a clock pulse is given, it adds the current value of the accumulator (let's call it a) and a given 4-bit input b. the b input is provided using 4 input switches. thus, the accumulator stores the addition of multiple 4-bit values provided to the alu -draw the circuit/logic diagram.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

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.

Which from the following instrument is commonly used to detect the high pitch butzing sound in bearings? [clo4] a)-digital ultrasonic meter b)-infrared camera c)-spectroscopic d)-vibrometer
