Overview: Most people don’t know that the human body is just one huge collection of vectors. Some of these are position vectors, some are force vectors, and some are torque vectors. The relationship between these vectors determines things like whether or not you can lift a piece of furniture without throwing your back out. People who study physical therapy and medicine are especially in tune with how the balancing of these vectors determines physical health and good functioning of the body. In this lab, we will begin the process of seeing the parts that make human (and animal) bodies can actually be described as vectors.

Can you please look at the attached pictures find the Humerus, Radius, Femur, Tibia (both left and right sides). Treat each bone as a vector beginning at one joint and ending at the other (you can choose, but be careful about negative signs). Then find the x and y components of each bone vector in units of centimeters using a ruler. Once you have the components, express each vector in (i,j) notation. Lastly, once you have each bone in vector notation, find the magnitude and direction of each bone vector. Four vectors for each picture are needed, along with notes and calculations.
