[#61] A compound truss may be formed by connecting two simple rigid frames, by
Correct Answer

(B) Three bars

[#62] If a three hinged parabolic arch, (span $$l$$, rise h) is carrying a uniformly distributed load w/unit length over the entire span,
Correct Answer

(D) All the above

[#63] Keeping breadth constant, depth of a cantilever of length $$l$$ of uniform strength loaded with uniformly distributed load w varies from zero at the free end and
Correct Answer

(B) $$sqrt {frac{{3{ ext{w}}}}{{sigma { ext{b}}}} imes l} { ext{ at the fixed end}}$$

[#64] A cantilever of length ‘L’ is subjected to a bending moment ‘M’ at its free end. If E$$I$$ is the flexural rigidity of the section, the deflection of the free end, is
Correct Answer

(D) $$frac{{{ ext{M}}{{ ext{L}}^2}}}{{3{ ext{E}}I}}$$

Explanation

Solution: $$left(frac{2}{3}
ight)^3$$

[#65] A cantilever of length 2 cm and depth 10 cm tapers in plan from a width 24 cm to zero at its free end. If the modulus of elasticity of the material is 0.2 × 10 6 N/mm 2 , the deflection of the free end, is
Correct Answer

(D) 5 mm
