Between any two points: - Area under load = difference in shear - Area under shear = difference in moment - Slope of shear curve = - (load trend) - Slope of moment curve = shear trend. No external force acts upon the FG beam, and the beam was at- tached to a rigid hub that rotated with constant angular speed. The programme in Digital Management comprises three main areas of study: business. Both rotation and scaling are linear transformations on the coordinates of the object’s points. In Section 4, using a resonance overlap criterion, we calculate how large the perturbing wave needs to be to cause largescalestochasticity. The relevant Hilbert space has dimension 2j+1 and the observables for the three projections of angular momentum on three orthogonal directions (in a right-handed configuration) can be expressed as in the above special case (j=½) using the counterparts of Pauli matrices in a Hilbert space of 2j+1 dimensions, namely three 2j+1 by 2j+1 matrices.
