A homogeneous bar, pinned at a distance a from one end, with total length, L, is subjected to gravity loading
and released from rest at an angle θ = 30° from the vertical. The rotational speed when it passes through θ = 0°
is calculated and compared to an analytical expression. Figure E5.1 Pinned Bar Under Gravity Loading Problem Sketch ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 3–10 VME5
Density = 1.0 kg/m3
Modulus of Elasticity = 10E6
Poisson's Ratio = 0.30 Geometric Properties
Constant square cross-section
of 0.1 x 0.1 m2
L = 1.0 m;
a = 0.25m Loading
The acceleration due to gravity is 9.8 m/s2
in the y-direction. One node is constrained
in UX, UY, and UZ. All other nodes constrained only in UZ.
At y = 0 UY = 0 Analysis Assumptions and Modeling Notes
The material properties were selected arbitrarily. As noted in W. G. McLean, E. W. Nelson, C. L. Best, Schaum's
