The coefficient of static friction between the friction pad at B and the flywheel is 0.4. 8/12 Hib 0.6 m 1m 30 IB 60 mm 0.3 m M = 300 N-mHold your upper arm vertical and your lower arm horizontal with your hand palm-down on a table, as shown below. If you now push down on the table, you'll feel that your triceps muscle has contracted and is trying to pivot your lower arm about the elbow joint. If a person with the arm dimensions shown pushes down hard with a 12-lbs force, what force must the triceps muscle provide, in Ibs? Ignore the mass of the arm and hand in your calculation. (Hint: Where should you choose as the pivot point?) Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Triceps 30 cm 2.4 cm
