Hybrid Bearing

This work aims to design a magnetic suspension for an experiment to measure gravitys velocity. Such device must rotate two objects symmetrically with the greatest mass and largest radius as possible, at the speed of [Formula: see text], which means this device falls into the high-speed machines category. The guidelines and solutions proposed in this paper constitute a contribution to this class of engineering problems and were based on an extensive literature search, contacts with experts, the tutors and author’s experience, as well as on experimental results. The main solution proposed is a hybrid bearing that combines a radial passive magnetic bearing with an axial sliding bearing, here called MPS (Magnetic Passive and Sliding) bearing.

Two Bodies

We propose a simple experiment to measure the speed of gravity in the laboratory. A moving body induces changes in the gravitational field that travel to the detector with a finite time delay. Moving two bodies causes changes to the gravitational field. These changes can add or subtract, and observing this interference allows for the measurement of the speed of gravity.

Short Comment

The observation of Shapiro time delay of quasar light passing near Jupiter1 generated considerable excitement, but also considerable controversy. The disagreements involve two distinct issues: (i) Is there a vJ/c term in the time delay that is large enough to detect? (ii) If so, is the factor of c in the delay the "speed of gravity" cg or the "speed of light" c? I will comment briefly on each.
