Figure 4–5a shows a cantilever beam with an end load. Normally we model thisproblem by considering the left support as rigid. After testing the rigidity of thewall it was found that the translational stiffness of the wall was kt force per unitvertical deflection, and the rotational stiffness was kr moment per unit angular(radian) deflection (see Fig. 4–5b). Determine the deflection equation for the beamunder the load F.
