- A rolled steel joist is simply supported at its ends and carries a uniformly distributed load which causes a maximum deflection of 10 mm and slope at the ends of 0.002 radian. The length of the joist will be,
- Pick up the correct statement from the following:
- Maximum strain theory for the failure of a material at the elastic limit, is known as
- A body is said to be in equilibrium if
- A close coil helical spring of mean diameter D consists of n coils of diameter d. If it carries an axial load W, the energy stored in the spring, is
- A two hinged parabolic arch of span l and rise h carries a load varying from zero at the left end to ? per unit run at the right end. The horizontal thrust is
- The maximum deflection due to a load W at the free end of a cantilever of length L and having flexural rigidity EI, is
- The ratio of moments of inertia of a triangular section about its base and about a centroidal axis parallel to its base, is

A.
In a loaded beam, the moment at which the first yield occurs is called yield moment |
|
B.
In a loaded beam, the moment at which the entire section of the beam becomes fully plastic, is called plastic moment |
|
C.
In a fully plastic stage of the beam, the neutral axis divides the section in two sections of equal area |
|
D.
All the above |
