-
In the working stress method of IS 456, the modular ratio m is taken as:
सही उत्तर: घ) 280/(3σcbc)
IS 456 specifies m = 280/(3σcbc), where σcbc is the permissible compressive stress in concrete in bending; it partly accounts for long-term creep.

As per IS 456:2000, the maximum spacing of vertical stirrups in a beam shall not exceed:
सही उत्तर: ग) 0.75d or 300 mm, whichever is less
IS 456 limits the spacing of vertical stirrups to 0.75d or 300 mm, whichever is less, where d is the effective depth.

As per IS 456:2000, the effective flange width of a T-beam (monolithic with slab) is taken as the lesser of the actual width and:
सही उत्तर: ख) lo/6 + bw + 6Df
IS 456 clause 23.1.2 gives bf = lo/6 + bw + 6Df for T-beams (lo/12 + bw + 3Df for L-beams), where lo is the distance between points of zero moment.

Compared with a solid shaft of the same material, length and weight, a hollow circular shaft:
सही उत्तर: क) Can transmit a greater torque
For the same area, the hollow shaft places material farther from the axis, giving a larger polar moment of inertia and thus greater torque capacity.

-
Creep of a material is best defined as:
सही उत्तर: घ) Gradual increase of strain with time under a constant sustained stress
Creep is time-dependent deformation under sustained constant stress, important in concrete and in metals at high temperature.

-
In a tensile test, the ductility of a material is commonly expressed by its:
सही उत्तर: घ) Percentage elongation and percentage reduction in area at fracture
Ductility is the ability to deform plastically before fracture, measured by percentage elongation and reduction in area.

-
Which theory of failure is generally considered the most suitable for ductile materials?
सही उत्तर: ख) Maximum distortion energy (shear strain energy) theory (von Mises)
Experiments show ductile metals yield in agreement with the distortion energy (von Mises) theory; Rankine's theory suits brittle materials.

An element is in a state of pure shear with shear stress τ. Its principal stresses are:
सही उत्तर: क) +τ and −τ, on planes at 45° to the shear planes
Mohr's circle for pure shear is centred at the origin with radius τ, giving σ1 = +τ and σ2 = −τ on planes inclined at 45°.

-
The axial deflection of a close-coiled helical spring with mean coil radius R, wire diameter d, n active turns and modulus of rigidity G under load W is:
सही उत्तर: ग) 64WR³n/(Gd⁴)
Deflection δ = 64WR³n/(Gd⁴), which is equivalent to 8WD³n/(Gd⁴) in terms of mean coil diameter D.

-
The stress produced in a bar by a suddenly applied axial load is how many times the stress produced when the same load is applied gradually?
सही उत्तर: ग) Twice
Equating work done P·δ to strain energy σ²AL/(2E) for a sudden load gives σ = 2P/A, twice the gradual-load stress P/A.
