Analysis of Figures 5 and 6 shows a horizontal structural resonance on the outboard bearing housing at 424 Hz (approximately equal to vane passing frequency) which does not appear on the pump body. Figure 7 shows the vertical structural resonance of the outboard bearing to be somewhat below vane passing frequency.

Generalizing the structure of planar trusses to 3D results in space trusses. The most elementary 3D space truss structure is the tetrahedron. The members are connected with ball-and -socket joints. Simple space trusses can be obtained by adding 3 elements at a time to 3 existing joints and joining all the new members at a point.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
