While you're studying for your KNES $363$ exam, you decide to quantify how much of a pain in the neck it really it$.$ You know that your head has a mass of $5$ kg and you've been statically hunched over at $37$ degrees for last few days causing an applying far too much force through your splenius capitis $(F_m)$ and cervical vertebrae $(F_v).$ Use the free body diagram to answer the questions below:

Assuming static equilibrium, calculate the force applied by your splenius capitis $(F_m)$ and cervical vertebrae $(F_v)$

Assuming static equilibrium, calculate the axial $($normal$)$ force and bending moment acting at the centre of the cross section labeled $S_1-S_2.$

Calculate the normal stress on the surface of the cross section at points $S_1$ and $S_2.$ Assume the crosssectional area and areal moment of inertia are $50m{m}^2$ and $180m{m}^4,$ respectively.
