Even when the head is held erect, as shown in the figure, its center of mass is not directly over the principal point of support (the atlanto-occipital joint, Point A). The muscles at the back of the neck should, therefore, exert a force to keep the head erect. That is why your head falls forward when you fall asleep in the class. If the head weighs 55 N, calculate the force exerted by the muscles ?M using the information in the figure. Assume that ?1=5.3 cm, ?2=2.5 cm, and ∣∣?⃗ w∣∣=55 N. What is the force FJ exerted by the pivot on the head?

Hi, I am in physics I and I'm trying to understand this word problem. It saids that a 6.0-m uniform board is supported by two sawhorses 4.0m apart. A 32kg child walks on the board to 1.4 m beyond the right support when the board start to tip. a.) Find the mass of the board b.) Then he walks back 0.40m and stands still. Find the forces exerted by the supports at this time. (use the mass found in part a). Please be detailed of how this works. Its a harder problem for me to understand. Thank you!
Consider a rigid steel beam of length L = 11.5 m and mass mb = 405 kg resting on two supports, one at each end. A worker of mass mw = 76 kg sits on the beam at a distance x from support A. Refer to the figure. a)When the worker sits at a distance x = 4.5 m from support A, calculate the force, in newtons, that support B must exert on the beam in order for it to remain at rest. Use g with three significant figures. b)The force exerted on the beam by support A is measured and found to be FA = 2180 N. At what distance x, in meters, from support A is the worker sitting now?
