Q28. | 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 = 2Number of reactions = 4
so, Indeterminacy = 4 -2 = 2

Q29. | 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 : PL3/3EI = wL4/8EI
So, P = 3/8 (wl) =( 3/8) x 800 = 300 kN
