The lift force per unit span length on an aircraft wing is given
by following function:
where L0 is the magnitude of the lift at the
centerline and b is the span length. Determine the Shear force(V),
Moment(M) and Displacement(w) as a function of x. The centerline of
the wing is located at x = 0 and the wing can be assumed to be
cantilevered at that point.
