The telescopic cantilever beam is widely used in different types of cranes. These
structures are flexible; it can expand or shrink according to the operating conditions. The
dynamic changes of the total length of the structure lead to time-dependen
t vibrational
characteristics. In practice, CAD modeling for this case is a challenging matter due to the
nature of the problem of analyzing stress and deformation occurring during the operation
of the crane. This research discusses the feasibility of finding a solution for the design
problems initialized during the failure of the telescopic cantilever beam through the
application of Finite Element Analyses (FEA) in order to find the ideal dimension of the
structure which represents the best design for the telescopic cantilever beam.
