Tote boxes are conveyed over a distance of 200 using a combination of two 100-long belt conveyors. Both are roller supported using 2.5 rollers weighing 5 lb each and installed on 6 centers. The WBR dimension is 33 for both conveyers. A conveyor speed of 150 fpm is used on the first conveyor, which feeds the tote boxes onto the second conveyor operating at a speed of 250 fpm. Each tote box is 20 long and weighs 40 lb loaded. The spacing between tote boxes on the first conveyor is 6 .

a. Determine the load on the first conveyor.

b. Determine the load on the second conveyor.

c. What should be the maximum roller center for stability of the tote boxes?
