A Computer main memory can store 2^64 words where each word is 2 bytes long. Cache memory in computer can have storage of 128 words in one block and cache memory is 2^28, for memory mapping 4-way set associative technique is used. Computer generates 48 bit logical address. The number of bits for TAG, SET, OFFSET will be:
(a) 15,26,7
(b) 20,19,7
(c) 18,23,7
(d) None of these

A vehicle for landing on the moon has a mass of 4500kg. The damped spring undercarriage system of the vehicle has a stiffness of 450kn/m and a damping ratio of 0.2. The rocket lift engines are cut off when the vehicle is hovering at an altitude of 10m. Calculate the max deflection of the undercarriage system when the vehicle hits the surface. On the moon the gravitational acceleration is 1.6 m/s2.

a roller at point A and a pin at point B support a uniform beam that has a mass 25.0 . The beam is subjected to the forces = 50.0 and = 79.0 . The dimensions are = 0.750 and = 2.30 . What are the magnitudes and of the reaction forces and at points A and B, respectively? The beam's height and width are negligible.

What is the flow rate in GPM (gallon per minute) for the water to run through each of the reversible turbine generator (6 of them) in Ludigton’s hydro pumped system, assuming the average height at 300 ft and 312 MW power rating for each generator. How long will it take to drain the entire reservoir with a capacity of 27 billion gallons?
a. What is the energy generated (or stored) per second? (E = PT)?
b. What is the meter equivalence to the 300 ft height (h)?
c. What is the potential energy of 1 liter (one kg) of water stored in the reservoir (P.E. = mgh), g = 9.8 m/sec2?
d. How many liters of water is needed to generated (or stored) the amount of energy in part (a)?
e. What is the gallon equivalence of answer from part (d)?
f. What is the flow rate in gallon per second ?
g. What is the flow rate in gallon per minutes?
h. What is the flow rate in gallon per hour?
i. What is the result by dividing the capacity of the reservoir by the answer you get from part (h)?
