Alternatively, it may be Fig. A possible solution to this problem is to divide the beam in several shorter beams, each one with a different cross section. Because the beam is pinned to its support, the beam cannot experience deflection at the left-hand support. Cantilever beams can be analyzed in 3 different ways namely static, dynamic and transient analysis.
