Question 3 1 pts Let's first start with the head and neck from the provided data. You should note that the top of the head is located at (712, 1040) and the mid-shoulder is (684, 954). The length of the head and neck area is the distance between these two points. Going along with the description from the previous prompt related to using the segmental approach, we would want to identity the mass of the head and neck area first. Since this male is 70 kg and the head and neck area is 8.26% of the body, we can identify the segment mass to be 5.782 kg (i.e. 70 kg x 0.0826). Each segmental mass will be used at the very end of the case study, but find the mass first to ensure you do not forget this step! Next, we can solve for the location of the center of mass using our coordinates. We will first look at the x coordinates. As identified in the video lecture, we assess the center of mass as the proximal coordinate - (length of the segment x the % location). Be sure to ALWAYS check your coordinates to assess if this makes sense. If you find that your calculated segmental center of mass is way outside of where the segment is located, you likely calculated the distance of the segment incorrectly. In general, the length of the segment should be the proximal end minus the distal end but this might be incorrect depending on how the body is positioned. In some instances where distal and proximal terms on not used, we can replace them with superior and inferior (i.e. inferior minus superior --- this is the case for the head and neck region). Therefore, ALWAYS check your work and ask yourself "is this reasonable and is this complete?" You can enter your data into the excel file provided and then select "FBD" at the bottom of the excel document to see a visual of your data points on the free body diagram. If your visual center of mass does not seem to be accurate, return to your math and make sure you are correctly identifying the lengths... think back to the content from triangles and basic trigonometry. Report the locations of the center of mass for the x and y coordinates of the head and neck region (Hint: you will need to complete a calculation for the x coordinates and a calculation for the y coordinates). You should use the equation: Mid-shoulder location - ((Mid-shoulder location - top of head) x % location). Remember, percent location was a predetermined value that was identified in the tables in the prior question and shown in the video lecture.
