Determine:

Area of the tube.

Determine $S.$

Calculate maximum moment.

Given: $4$ pieces of A$36$ steel are welded together to form a $66\mathrm{.}250-$inch tube.

$($corners are $100\%$ welds$)$

Determine:

Calculate $S$ using POGS

Calculate maximum moment.

Calculate $S$ using the I Method

Calculate maximum moment.

Given: Problems $1$ and $2$

Determine:

Are all three $S$ values be the same?

If they are or are not the same $S$ value. Why?

Are all three moments the same?

If they do or do not generate the same moment. Why?

What conclusions can you deduce?
