Question:

Currently eighty-five percent of all neck injuries are caused by rear-ends car collisions. To alleviate this problem, an automobile seat restraint has been developed that provides additional pressure contact with the cranium. During dynamic tests the of load on the cranium has been plotted and shown to be parabolic. Determine the equivalent resultant force and its location, measured from point A.
Given:
a = 0.5 ft
w0 = 12lb/ft
k = 24lb/ft3
w(x) = w0 + kx2

(X)M- W.
