10. Give the procedure for analyzing the continuous beams with fixed ends using three moment equations? CE8402 Important Questions Strength Of Materials 2 SOM2
The three moment equations, for the fixed end of the beam, can be modified by
imagining a span of length l 0 and moment of inertia, beyond the support the and applying the
theorem of three moments as usual.
11. Define Flexural Rigidity of Beams. CE8402 Important Questions Strength Of Materials 2 SOM2
The product of young‟s modulus (E) and moment of inertia (I) is called Flexural Rigidity
(EI) of Beams. The unit is N mm
2
.
12. What is a fixed beam?
A beam whose both ends are fixed is known as a fixed beam. Fixed beam is also called as CE8402 Important Questions Strength Of Materials 2 SOM2
built-in or encaster beam. Incase of fixed beam both its ends are rigidly fixed and the slope and
deflection at the fixed ends are zero.
13. What are the advantages of fixed beams?
(i) For the same loading, the maximum deflection of a fixed beam is less than that of a
simply supported beam.
(ii) For the same loading, the fixed beam is subjected to lesser maximum bending
moment. CE8402 Important Questions Strength Of Materials 2 SOM2
(iii) The slope at both ends of a fixed beam is zero.
(iv) The beam is more stable and stronger.
14. What are the disadvantages of a fixed beam?
(i) Large stresses are set up by temperature changes.
(ii) Special care has to be taken in aligning supports accurately at the same lavel.
(iii) Large stresses are set if a little sinking of one support takes place.
(iv) Frequent fluctuations in loadingrender the degree of fixity at the ends very uncertain. CE8402 Important Questions Strength Of Materials 2 SOM2
