A
only shear stress
B
only tensile stress
C
both shear and tensile stress
D
none of shear or tensile stress

Explanation

When a load is applied in the plane of the connection, rivets resist the load primarily through shear stress across their cross-section.

A
wood
B
steel
C
aluminum
D
concrete

Explanation

Trusses rely on members being in tension or compression. Concrete is very weak in tension and heavy, making it unsuitable for standard truss members compared to steel or wood.

A
chalk
B
lime
C
clay
D
lime putty

Explanation

Distemper is a water-based paint where the base material is typically chalk (whiting), mixed with water and a binder like glue or casein.

A
equal to
B
directly proportional to
C
inversely proportional to
D
independent of

Explanation

Bending stress (σ) is directly proportional to the distance (y) from the neutral axis, according to the flexure formula σ = My/I.

A
impervious
B
durable
C
stable
D
all of these

Explanation

A good road surface must be impervious (to prevent water damage), durable (to withstand traffic), and stable (to maintain shape).

A
10-15%
B
15-20%
C
20-25%
D
25-30%

Explanation

Concrete is strong in compression but weak in tension. Its tensile strength is generally estimated to be about 10% to 15% of its compressive strength.

A
modulus of rigidity
B
balk modulus
C
feexaral rigidity
D
torsional rigidity

Explanation

The term EI, where E is Young's Modulus and I is the Moment of Inertia, is called Flexural Rigidity. It represents the resistance of a beam to bending.

A
displacement
B
load
C
slope
D
moment

Explanation

In the method of virtual work (unit load method), we apply a virtual (imaginary) unit load or displacement to find the real displacement or force. The displacement is the virtual quantity in the principle of virtual displacements.

A
250 ppm
B
350 ppm
C
450 ppm
D
550 ppm

Explanation

According to WHO and many national standards, the desirable limit for chloride in drinking water is 250 mg/L (ppm) to avoid salty taste and corrosion.

A
পিজোমিটার
B
ইউটিউব
C
বার্ডনাটিউব
D
ম্যানোমিটার

Explanation

পিজোমিটার (Piezometer) হলো একটি সাধারণ যন্ত্র যা তরলের অল্প থেকে মাঝারি চাপ পরিমাপ করতে ব্যবহৃত হয়। এটি একটি খোলা নল যা তরলের উচ্চতা দিয়ে চাপ নির্দেশ করে।
