(a) 5 hours
(b) 4 hours
(c) 5.5 hours
(d) 2.5 hours

Q2. The detachment of the paint film from the surface is known as____________.
(a) Chalking
(b) Cracking
(c) Flaking
(d) Wrinkling

Q3. What will be the thermal stress developed in a rod having a diameter of 4 cm and length of 2m. it experiences heating from temperature 50°C to 200°C. the coefficient of thermal expansion is:
α=10×10^(-6) \/°C and young modulus is 250 GPa
(a) 300
(b) 325
(c) 350
(d) 375

Q4. The scale in which three successive dimensions can be measure at a time is called ___________.
(a) Chord scale
(b) Diagonal scale
(c) Plain scale
(d) Vernier scales

Q5. When not specified, the volume of steel in R.C.C work is taken as:
(a) 1% to 1.6% of R.C.C. volume
(b) 2% to 4% of R.C.C. volume
(c) 4% to 6% of R.C.C. volume
(d) 0.6% to 1% of R.C.C. volume

Q6. Enoscope is used to determine
(a) Spot speed
(b) Average speed
(c) Travel time
(d) None of these

Solutions

S1. Ans.(a)
Sol. Given,
Length (L) = 4m.
Breadth (B) = 2 m.
Depth (D) = 2.5 m.
Discharge (Q) = 4 × 10³ l/hour
Detention time of tank (t_d) =?
t_d = (Volume of tank (V))/(Discharge (Q) )
= (4×2×2.5 (m^3 ))/(4×10^3×10^(-3) (m^3 \/hour) )
= 5 hours.

S2. Ans.(c)
Sol. There are same defect in paint surface
(a) Flaking → It is detachment of paint film from surface.
(b) Chalking → Paintfill becomes powder due to insufficient oil.
(c) Blistering → Formation of bubble on the surface of paints.
(d) Cracking → Formation of crack on painted surface.

S3. Ans.(d)
Sol. Thermal stress in rod
σ_thermal=α∆TE
=10×10^(-6)×(200-50)×250×10^9
=375 MPa

S4. Ans.(b)
Sol. Diagonal scale → In this scale three successive dimension can be measured at a time like meter, decimeter and centimeter. In this case only units, tenths and hundredths can be shown.
Plane scale → In this scale two successive dimension can be measure at a time. Like meter and decimeter.

S5. Ans.(d)
Sol. The volume of steel in R.C.C. Works is taken as 0.6 to 1% of R.C.C volume (when not specified).

S6. Ans.(a)
Sol. Enoscope or mirror box method is used to determine spot speed.
