# Strength of Materials Questions and Answers – Analyse Indeterminate Beam

This set of Strength of Materials Multiple Choice Questions & Answers (MCQs) focuses on “Analyse Indeterminate Beam”.

1. A beam which is supported on more than two supports is called as______
a) Fixed beam
b) Continuous beam
c) Cantilever beam
d) Simply supported beam

Explanation: A beam which is supported on more than two supports is known as a continuous beam. The intermediate supports of a continuous beam are always subjected to some bending moment.

2. Which of the following them is also known as multi span beam _______
a) Cantilever beam
b) Simply supported beam
c) Fixed beam
d) Continuous beam

Explanation: A continuous beam is a beam which is supported on more than two supports. It is also known as multi span beam. The degree of indeterminacy depends upon the number of supports and nature of supports.

3. In deflection of a continuous beam, when loaded there will be convexity upwards over _________ supports.
a) End
b) Alternate
c) Intermediate
d) Every

Explanation: When a continuous beam is loaded, the deflection of the beam takes place along the intermediate supports with convexity upwards.

4. The _________ is more over the supports then at midspan in continuous beams.
a) Slope
b) Bending moment
c) Deflection
d) Shear force

Explanation: The bending moment is more over the supports then at midspan in case of continuous beams and hence the weight of the beam does not materially affect the stresses in the beam.

5. Moment distribution method is also known as __________
a) Hardy Cross method
b) Macaulay’s method
c) Mohr’s Theorems method
d) Kennedy’s theory

Explanation: The moment distribution method is evolved by professor Hardy cross in 1932 and can be used with advantage to analyse statically indeterminate structures and frames with rigid joint this method is simple and involves a process of relaxation.

6. Which of the following device is not based on Bernoulli’s equation?
a) Venturimeter
b) Orificemeter
c) Hydraulic lift
d) Pitot tube

Explanation: Bernoulli’s equation is applied to incompressible liquid flow where energy consideration is involved. Some of the hydraulic devices which are based on Bernoulli’s equation are venturimeter, orificemeter, Pitot tube.

7. Pascal’s law is applied in ____________
a) Pitot tube
b) Hydraulic lift
c) Orificemeter
d) Venturimeter

Explanation: Hydraulic lift is an example of Pascal’s law. According to Pascal’s law the “At a given point, the force is applied in all directions” and the rest are the examples of Bernoulli’s equation.

8. Which of the following devices measures the velocity of flow?
a) Pitot tube
b) Venturimeter
c) Orificemeter
d) Hydraulic jacks

Explanation: A pitot tube is a device which is used for measuring the velocity of flow at any point in a pipe or channel. It is based on the principle that if the velocity of flow at any point becomes zero, the pressure there is increased due to the conversion of kinetic energy into pressure energy.

9. Which of the following is the coefficient of pitot tube?
a) 0.96
b) 0.98
c) 0.97
d) 0.95

Explanation: The velocity (V) = Cv (2gh)1/2.
Where Cv = coefficient of pitot tube = 0.98
h= difference between liquid levels in the pitot tube and piezometer.

10. Bernoulli’s equation is applicable only for ___________ flow.
a) Rotational
c) Compressible

Explanation: The Bernoulli’s equation has been derived on the assumption that the velocity is uniform over the section. The Bernoulli’s equation is applicable only for steady, incompressible and irrotational flows.

11. Flow of water when a tap is just open is an example of __________ flow.
a) Uniform
d) Turbulent

Explanation: The flow is said to be unsteady if at any point in flowing liquid any one or all flow characteristics change with time liquid that is flowing at a changing rate as in the case. The flow in the tap is just opened is a perfect example for unsteady flow.

12. A Straight cantilever of uniform area carries a udl over its entire length. If the free end of a cantilever is now prop at the level of the fixed end, the vertical force required at the prop be __________
a) 3/4 W
b) 3/8 W
c) 5/8 W
d) W

13. ____________ is used to empty a tank of water having no outlet.
a) Venacontracta
b) Syphon
c) Summit
d) Dyne

Explanation: A syphon is used to connect two different elevations separated by a mountain
They also used to supply water to a town over a ridge and supply type of water having an outlet.

14. Find out the elongation of a tie of 2m long, if the axial rigidity is 5000 × 104 mm2. The axial pull be 20 kN.
a) 0.8 mm
b) 0.6 mm
c) 0.5 mm
d) 1mm

Explanation: Axial pull 20000N.
Elongation : Pl/ AE
Change in length = PL/ AE
= 20×10/500×11÷103.

15. Glass is an example of _________
a) Elastic
b) Brittle
c) Toughness
d) Hardness

Explanation: Brittleness is a property of a material by which It Breaks without much deformation produce his property generally considered to be highly objectionable in engineering.
