##### A 32 bit microprocessor has the word length equal to ------ .
 1) 2 bytes 2) 1 byte 3) 4 bytes 4) 8 bytes 5) None of these
##### Signal flow graph is used to obtain the ------ .
 1) stability of the system 2) transfer function of the system controllability of the system 3) observability of the system 4) controllability of the system 5) None of these
Answer : transfer function of the system controllability of the system
##### The bandwidth needed for transmitting  4 kHz signal using PCM with 128 quantising levels is -----
 1) 4 kHz 2) 16 kHz 3) 28 kHz 4) 64 kHz 5) None of these
##### The proper and accurate measurement of concrete ingredients for uniformity of proportion, is known as -----
 1) grading 2) curing 3) mixing 4) batching 5) None of these
##### A beam fixed at the and subjected to lateral loads only is statically indeterminate and degree of indeterminacy is ------- .
 1) 1 2) 2 3) 3 4) 4 5) None of these
Explanation : Number of equations = 2
Number of reactions = 4
so, Indeterminacy = 4 -2 = 2
##### A cantilever beam of span L is subjected to a downward load of 800 kN uniformly distributed over its length and a concentrated upward load P at its free end. For vertical displacement to be zero at the free end, the value of  P is -----.
 1) 300 kN 2) 500 kN 3) 800 kN 4) 1000 kN 5) None of these
Explanation : PL3/3EI = wL4/8EI

So, P = 3/8 (wl) =( 3/8) x 800 = 300 kN
##### The symmetry of stress tensor at a point in the body under equilibrium is obtained from ------.
 1) conservation of mass 2) force equilibrium equations 3) moment equilibrium equations 4) conservation of energy 5) None of these
##### A cantilever beam curved in plain and subjected to lateral loads will develop at  any section.
 1) BM and SF 2) BM and twisting moment 3) Twisting moment and SF 4) BM, twisting moment and SF 5) None of these
Answer : BM, twisting moment and SF
