None of these
The necessary condition for the equilibrium of a body is
LV 0
LH
LM
All of these
The members which support the covering material of a sloping roof are
Rafters
Purlins
Battens
Struts
If a material has identical elastic properties in all directions, it is said to be
Homogeneous
Isotropic
Completely elastic
None of these
The effective length of a column having length and one end fixed and the other end hinged is given by
O·65L
1·2L
O·8L
1·5 L
Modulus of rupture of a material is a measure of
compressive strength

Define ductile and brittle materials. Discuss how a ductile material is better as compared to a brittle material.
Differentiate between long and short columns. Discuss the factors affecting strength of a column. Explain the failure of short columns.
Derive the expression for shear stress in a circular cross-section of a beam. Also prove that the maximum shear stress is 1·33 times of the average shear stress.
A simply supported beam of span of 5 m is loaded with a UDL of 6 kN/m over the entire span. The beam has a rectangular cross-section of 150 mm width and 250 mm depth. Calculate the maximum bending stress in the beam.
Explain the importance of deflection in a structure. Discuss briefly the necessity of computation of deflections.
