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.

-
The strain energy stored per unit volume of a material when it is stressed up to its elastic limit is called the:
सही उत्तर: ख) Modulus of resilience
Proof resilience is the total maximum strain energy up to the elastic limit; per unit volume it is called the modulus of resilience.

Under the Environment Protection Act, 2076 of Nepal, the least detailed level of environmental study prescribed for proposals with relatively minor impacts is the:
सही उत्तर: क) Brief Environmental Study (BES)
The Environment Protection Act, 2076 provides three levels of study: BES (least detailed), IEE and EIA (most detailed).

-
Qualitative influence lines for reactions and internal forces, including in indeterminate structures, are conveniently drawn using the:
सही उत्तर: घ) Müller-Breslau principle
The Müller-Breslau principle states that the influence line for a force is the deflected shape obtained by removing its restraint and applying a unit displacement.
