the point indicated:
Point J.
PROBLEM 7.6
For the frame and loading shown, determine the internal
forces at the point indicated:
Point K.
PROBLEM 7.7
An archer aiming at a target is pulling with a 45-lb force on the
bowstring. Assuming that the shape of the bow can be approximated
by a parabola, determine the internal forces at Point J.
