Adding lengths (total length of bent bar)

[adiospotato]

I cant figure out how to find the total length of this bent bar. anyone?

What are your thoughts? What have you tried? How far have you gotten? Where are you stuck?

Also, does "\(\displaystyle \emptyset\)" indicate "radius of the curve", with the number following being possibly measured in degrees? And are you supposed to be finding a "real world" value, or will "mathematically ideal" be good enough? (The instructions for this exercise should tell you, or else just use whatever your instructor used in class or your book used in this section.)

Please be complete. Thank you!

the \(\displaystyle \emptyset\) indicates the bars diametre which is 20mm. I need a real world value to find the length of the bar when it is straight (I am making that in real life) I just cant do the lengths that curve

the \(\displaystyle \emptyset\) indicates the [bar's] diametre which is 20mm.

Then why does the diagram label the bar with Ø10 and the rollers with Ø20?

Okay. That "real life" value will depend upon things like how much the particular metal you're using has a tendency to stretch and compress, etc, which is obviously knowledge that retired math teachers are unlikely to have or be sure how to use.

To obtain the engineering info you're needing, please consider hiring a qualified local engineer to provide you with the contracting service you are requesting.

Good luck on your project!
