The paper towel dispenser carries two rolls of paper. The one in use is called the stub roll A and the other is the fresh roll B. They weigh 2 lb and 5 lb, respectively. If the coefficients of static friction at the points of contact C and D are(µs)C = 0.2 and (µS) D = 0.5, determine the initial vertical force P that must be applied to the paper on the stub roll in order to pull down a sheet.The stub roll is pinned in the center, whereas the fresh roll is not. Neglect friction at the pin
