Question:
F, = 300 N F. = fulcrum Use 21 cm 25 cm 29 cm this diagram to answer the question below. The diagram above shows lever mechanics during forearm flexion. N = newton, the SI unit of physical force. 1 N = 1 kilogram-meter/second2 Q. Use the information in the diagram to calculate the out-force generated during forearm flexion (biceps contraction). a. Length of the in lever is: ___ cm_ (0.5 pts) Length of the out lever is: __ cm____(0.5 pts) b. Calculate the lifting force (i.e., out force). Show all your work. N
