-
For a standard equal-leg fillet weld with a 90° angle between fusion faces, the effective throat thickness is taken as:
सही उत्तर: क) 0.7 times the size of the weld
Throat = size × cos 45° ≈ 0.707 s, commonly taken as 0.7 s.

In a steel roof truss, the plate used to join several members meeting at a joint is called a:
सही उत्तर: घ) Gusset plate
Gusset plates are used to connect truss members meeting at a joint.

In steel structures, a lug angle is used mainly to:
सही उत्तर: ख) Reduce the length of the end connection of an angle member
A lug angle connects the outstanding leg of an angle to the gusset, increasing connection capacity and so shortening the joint.

As per IS 800:2007 (limit state method), the partial safety factor for material against resistance governed by yielding (γm0) is:
सही उत्तर: क) 1.10
IS 800:2007 takes γm0 = 1.10 for yielding and buckling, and γm1 = 1.25 for resistance governed by ultimate stress.

A stone is dropped from rest and falls freely for 2 seconds (g = 9.81 m/s²). The distance fallen is:
सही उत्तर: ख) 19.62 m
s = ½gt² = 0.5 × 9.81 × 2² = 19.62 m.

On level ground and neglecting air resistance, a projectile attains its maximum horizontal range when projected at an angle of:
सही उत्तर: क) 45°
Range R = u² sin 2θ / g is maximum when sin 2θ = 1, i.e. θ = 45°.

For a body resting on a rough inclined plane, the maximum inclination at which it remains at rest without any applied force (angle of repose) is equal to the:
सही उत्तर: ग) Angle of friction
At the angle of repose the component of weight along the plane just equals limiting friction, giving tan α = μ = tan φ, so α = φ.

-
The coefficient of friction (μ) is related to the angle of friction (φ) by:
सही उत्तर: ग) μ = tan φ
The angle of friction is the angle whose tangent equals the ratio of limiting friction to normal reaction, so μ = tan φ.

Lami's theorem is applicable to a system of:
सही उत्तर: क) Three concurrent coplanar forces in equilibrium
Lami's theorem states that for three concurrent coplanar forces in equilibrium, each force is proportional to the sine of the angle between the other two.

Brief episodes of vertigo triggered by changes in head position are typical of BPPV. Which bedside test confirms it?
सही उत्तर: ख) Dix-Hallpike manoeuvre
The Dix-Hallpike manoeuvre provokes characteristic positional nystagmus in posterior canal BPPV.
