A spring is such that it would be stretched 8 in by a 4 lb weight and a damping force of
magnitude 0.5|𝑣| is added because of immersing the body in a thick liquid. Let the weight be
attached to a spring and pulled down 5 in below the equilibrium point. If the weight is started
with an upward velocity of 3.5 flt/sec, describe the motion. No impressed force is present.
In a pin jointed four bar mechanism ABCD, the lengths of various links are as follows:
AB= 25 mm; BC = 87.5 mm : CD=50 mm and AD = 80 mm. The link AD is fixed and the angle BAD = 135. If the velocity of B is 1.8 m/s in the clockwise direction, find 1. velocity and acceleration of the mid point of BC. and 2. angular velocity and
angular acceleration of link CB and CD.

Explain the Comparison of 3 mapping techniques between main memory to cache memory in the tabular form. show how and from where CPU will access the word from the cache memory in each mapping technique with the help of diagram. Take the word number as per your roll no. for example if your roll no is 35 than you have to show how and from where CPU will access W35 from the cache memory in case of each mapping technique with the help of diagram. Assume the main memory size as 16 KB, line size 128 bytes, cache size 1K bytes and k value is 4 .

Q2. A computer employs RAM chips of 128 x 8 and ROM chips of 512 x 8. The computer system needs 1K bytes of RAM, 2K bytes of ROM, and two interface units, each with two registers. A memory-mapped 1/0 configuration is used. The two highest-order bits of the 16 bit address bus are assigned 11 for RAM,
10 for ROM, and 01 for interface registers.
a. How many RAM and ROM chips are needed?
