An archer aiming at a target is pulling with a $45$ rl force on the bowstring.

Assuming that the shape of the bow can be approximated by a parabola. determine the internal forces at point $\backslash ($ J $\backslash )$

The axial force $\backslash ($ F $\backslash )$ is lb $-\backslash (\backslash$boldsymbol$\{\backslash$theta$\}\backslash )\backslash (0^\{\backslash$circ$\}\backslash ).$

The shear force $\backslash ($ V $\backslash )$ isb

:

The bending moment $\backslash ($ M $\backslash )$ islb $-$in$.$
