A polisher is started so that the fleece along the circumference undergoes a constant tangential acceleration of 5 m/s 2. Five seconds after a polisher is started from rest, small tufts of fleece from along the circumference of the 250-mm-diameter polishing pad are observed to fly free of the pad. At this instant, determine (a) the speed v of a tuft as it leaves the pad, (b) the magnitude of the force required to free a tuft if the average mass of a tuft is 1.5 mg. OFt -> 0.009, v -> 25., Ftan -> 9.*10^-6, Fnorm -> 0.009 Ft-> 0.009375, v -> 25., Ftan -> 7.5*10^-6, Fnorm > 0.009375 Ft -> 0.0075, v -> 25., Ftan -> 7.5 10^-6, Fnorm -> 0.0075 Ft-> 0.0192, v -> 40., Ftan -> 7.5*10^-6, Fnorm -> 0.0192

The next several problems utilize the same data given in this problem statement. I suggest you glance over the next few problems, so that you have an idea of the items you will need to calculate. You may determine that you calculate the items in an order other than that given on the test (doing this is OK!). BUT, be sure you look at EACH problem and provide the answer to that particular problem. Consider the bracket shown in Fig-3.
