Q2.  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 
Answer : 2
Explanation : Number of equations = 2
Explanation : Number of equations = 2
Number of reactions = 4
so, Indeterminacy = 4 2 = 2

Q3.  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 
Answer : 300 kN
Explanation : PL^{3}/3EI = wL^{4}/8EI
Explanation : PL^{3}/3EI = wL^{4}/8EI
So, P = 3/8 (wl) =( 3/8) x 800 = 300 kN
