IYPT 1994, Задачи на турнира — Задача 2. Compass

7th IYPT (1994)

Условие

Think up a problem yourself (problems 1, 2, 3). Invent yourself and solve a problem on the given theme.

“In sledge trips we use liquid compasses, the most exact of the small ones. But you understand of course that due to proximity to the magnetic pole the arrow usually points downwards. To make it horizontal, its opposite end is balanced with a weight.” (From the letter of Cherry-Garrad, member of the last expedition of R. Scott). Use the context of this quotation to formulate a problem.
