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

In summary, to calculate the face pressure on Roller 3, you will need to know the force pushing 1 and the surface area of Roller 3. The force should be measured in Newtons (N) and the area should be measured in square meters (m<sup>2</sup>). The surface area of Roller 3 can be measured by finding the circumference of the roller and multiplying it by the width of the roller. You can use a different force pushing 1 for the calculation as long as it is measured in Newtons and is pushing on the same surface area of Roller 3. The specific formula for calculating face pressure on Roller 3 is face pressure = force / area and can be applied to any situation where there

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.
