How to solve for face pressure on Roller 3 using the force pushing 1

AI Thread Summary
The discussion centers on solving for face pressure on Roller 3 using the force from Roller 1. Participants clarify that the inquiry may be homework-related and suggest moving it to a dedicated forum. Key steps to approach the problem include ensuring all units are correct, calculating the tension in the band, and creating a free body diagram for Roller 3. The forum emphasizes guidance without providing complete solutions. Engaging with these steps will facilitate a better understanding of the mechanics involved.

TL;DR Summary
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 'What type of toilet do I have?'

Thread 'What type of toilet do I have?'

I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...

Thread 'Thread No-Go plug gage allows 3 turns to enter. That's too many!'

After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
