2. Muscle can generate approximately 90 N of force per square centimeter of cross-sectional area. If a biceps brachii has a cross-sectional area of 10 cm2, how much force can it exert? ANSWER FOR PROBLEM 2 = 900 N 3. Using the same force/cross-sectional area estimate as in Problem 2, and estimating the cross sectional area of your own biceps brachii how much force should the muscle be able to produce
