Implement the 4-bit Ripple Carry Adder (RCA) for unsinged integers using the 1bFA from problem 1 as building blocks. The adder has 9 inputs A(3:0), B(3:0), C0 and 5 outputs S(3:0), C4. a) Show the schematic. b) Estimate the circuit propagation delays for • Carry-in C0 to Carry-out C4, • Data-to-Carry-out C4.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
