[#241] Brinell Hardness Number (BHN) for talc is approximately in the range of

(A) 1-5

(B) 20-30

(C) 100-150

(D) 200-250

Correct Answer

(A) 1-5

Explanation

Solution: Brinell Hardness Number (BHN) is a measure of the hardness of materials, with higher values indicating harder materials. Talc is a soft mineral, often used in cosmetics and as a lubricant. The BHN of talc is very low, typically falling within the range of 1-5 , indicating its softness compared to other materials.

(B) Production schedule

(C) Sales forecasting

(D) Quality control

Correct Answer

(B) Production schedule

(A) Body centred cubic (bcc)

(B) Hexagonal close packed (hcp)

(C) Face centred cubic (fcc)

(D) None of these

Correct Answer

(C) Face centred cubic (fcc)

(A) Anodic protection

(B) Cathodic protection

(C) Using inhibitors

(D) Using a special alloy resistant to corrosion

Correct Answer
