TL;DR: A band is wrapped around 4 rollers, assuming no tension change in the belt and no stretch, how can you solve for the face pressure / normal force on roller 3. The contact area on Roller three is 12 ft, and each roller is 80 inches in length

Is this homework? If so, we can move it to the homework forum.

This is PF, where we help you, but do not fully solve it for you. So, here's some help:

Step 1: Get all of your units correct.

Step 2: Calculate the tension in the band.

Step 3: Sketch and post a free body diagram for Roller 3.

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
