The dynamic study of rotors is usually performed under a number of assumptions, namely small displacements and rotations, small unbalance and constant angular velocity.
The element is based on a first-order shear deformation theory with large displacements, moderate rotations, small strains, material nonlinearity, and a Rayleigh type of viscoelastic damping.
The specimen-specific equivalent spatial mechanisms replicated the original passive motion very well, with mean discrepancies in position smaller than 2.5 mm and in rotation smaller than 1°.
According to Eq. (38) and at ρ2 > ρ1 the condition of RTI can be obtained easily from the constant term and it is given as ( Ω + 2 + k 2 Ω z 2 ) < 1 2 g k 3 A 1 + α, where the system remains unstable for all the values of rotation smaller than this value.
For lower stake examinations, for instance formative assessment within a clinical rotation, smaller panels can be used.
Major assumptions are as follows: straight beam neutral axis; horizontal rotation; small displacements but large overall rotations; in-plane deformation in the direction normal to the beam neutral axis and rigidity of added masses.
Experimental results show that the proposed algorithm has good performance for object tracking in crowded scenes on stairs, in airports, or at train stations in the presence of object translation, rotation, small scaling, and occlusion.
A backrub shifts the Cα Cβ orientation of a given side-chain by rigid-body dipeptide rotation plus smaller individual rotations of the two peptides, with virtually no change in the rest of the protein.
Maximum span:depth ratios are presented so that the required connection rotations are smaller than 20, 25 or 30 mRad respectively.
In the prosthetic designs studied, the amount of external rotation was smaller, was absent, or was reversed to internal tibial rotation during knee extension.
