Fundamental Natural Frequencies of Beams (bending) and Shafts (Torsion) The values for natural frequencies relate to cycle/unit time. The higher harmonic modes are not listed. To obtain values for wn in radians/s multiply values by 2.p. Cantilevered Beam ![]()
Simply Supported Beam ![]()
Beam with fixed ends
Beam with one end fixed and one end Simply Supported
Mass on Cantilever beam Note: Assume beam of negligible mass Central mass on Simply supported beam Note: Assume beam of negligible mass Mass on Simply supported beam. Off-Centre Note: Assume beam of negligible mass Multiple Mass on beam ![]() Formula for Combined Loading ![]() Mass on Cantilevered Shaft In Torsion Note: Assume shaft of negligible mass Shaft with mass at both ends Note: Assume shaft of negligible mass ![]() |
