-
In valuation of property, the 'years' purchase' for perpetual income at a rate of interest of 5% (ignoring sinking fund) is:
सही उत्तर: घ) 20
Years' purchase = 100 / rate of interest = 100/5 = 20; capitalised value = net annual income × YP.

Rankine's empirical formula for columns obtains the crippling load by combining the:
सही उत्तर: ग) Crushing load and Euler's buckling load
Rankine's formula is 1/P = 1/Pc + 1/Pe, combining the crushing load Pc and Euler load Pe, so it applies to short and long columns.

The slope at each support of a simply supported beam of span L carrying a UDL w per unit length over the whole span is:
सही उत्तर: ख) wL³/(24EI)
For a simply supported beam under full UDL, the end slope is θ = wL³/(24EI).

According to Castigliano's theorem, the partial derivative of the total strain energy of a linearly elastic structure with respect to an external load Pi gives:
सही उत्तर: क) The deflection at the point of application of Pi in its direction
Castigliano's theorem: ∂U/∂Pi = δi, the displacement of the load point in the direction of Pi.

For a plane stress state with σx = 60 MPa, σy = 20 MPa and τxy = 15 MPa, the radius of Mohr's circle is:
सही उत्तर: घ) 25 MPa
R = √[((σx − σy)/2)² + τxy²] = √(20² + 15²) = √625 = 25 MPa.

Two springs of stiffness 200 N/mm and 300 N/mm are connected in series. The equivalent stiffness is:
सही उत्तर: ग) 120 N/mm
For springs in series 1/k = 1/200 + 1/300 = 5/600, so k = 120 N/mm.

A three-hinged arch under general loading is:
सही उत्तर: ख) Statically determinate
The three equilibrium equations plus the condition of zero moment at the crown hinge give four equations for four reaction components, so it is determinate.

The radius of gyration of a solid circular section of diameter d about a centroidal axis is:
सही उत्तर: क) d/4
k = √(I/A) = √[(πd⁴/64)/(πd²/4)] = √(d²/16) = d/4.

Failure of a material under repeated cyclic stresses that are well below its static strength is known as:
सही उत्तर: घ) Fatigue
Fatigue failure occurs from crack growth under repeated or reversed loading even at stresses below the yield strength.
