Enter to 2 significant figures Mechanical Advantage: b) Improper posture and positioning of the head can lead to muscle tension headaches. If the head begins to shift forward while studying or reading, the center of mass moves further from the fulcrum or pivot point. It is a subtle change, but the figure below shows the head shifted forward. The center of mass for the weight of the skull is labeled W and the muscles that attach to the back of the skull are labeled M. Determine the new mechanical advantage of the skull muscles when d₁ = 16 mm…
