Re: Sunday Morning Puzzle.



bryan!

what do you mean by reconfigure? Both masses? (there are four)

bc who thought he was an "expert" on student use of the Cavendish (as
you point out, more correctly, Michell) pendulum. (The original papers,
were possible, are included in all the student exptl. files at UCSC.)

P.s. Eötvös used a resonance method to increase sensitivity. I've been
alternating the ext. masses to get the pendulum swinging from rest. It
takes so long to set the zero, I've hesitated rotating the pivot to
start the pendulum, but will try that method.

You decide to demonstrate an attraction of masses
using the Michell/Cavendish arrangement.

You wish to maximize the deflection produced by the
masses on each end of the balance arm, which are 15 cm lead spheres.

How could you reconfigure the movable external mass for this purpose?

How could you reconfigure both masses for the purpose?
