ANSWER:

Solution to 73P Here two vectors of equal magnitudes and denotes the pull given to the shoulder by the traction machine. The outward pull is the resultant of the two vectors. It is equal to 5.6N. Step 1 gives the magnitude of the resultant vector. Here magnitude of is equal to magnitude of
