Solution

I can answer for only these questions. The answer is based on what I understood from the question.

Question 1

The actual answer for web thickness of MC 6x18 is 0.379 in. which is mathematically near 0.40inch. So, from that point answer is option (D) is the answer.

Similarlly,

For Question 6. Answer- option (D)

The actual answer for Flange thickness of heaviest W14 shape is 4.910in. Which is mathematically nearlly equal to 5 inches.

For Question 10 Answer- option (A)

The plastic section modulus about y-y axis for MC18X58 is 10.7 cubic inch. After seeing option it is near to 10 inch. (mathematically)
