Elementary Mechanics Using Python

It is a familiar principle in elementary mechanics that a uniform motion of the whole system under consideration makes no difference to the phenomena, and may be ignored. For example, in calculating the motions of the planets round the sun, we do not need to pay any attention to the fact that the whole solar system is travelling towards the constellation Lyra. It does not seem to us that there is anything surprising or needing explanation in this principle; in fact, when we try to examine the idea of motion through an empty space without fixed landmarks, we are conscious of something illusory in the conception.

Ice Forces

AbstractWhen large masses of ice, for example in the form of glaciers or floating ice fields, are moving against an obstruction, either natural or man-made, huge forces will develop. It is possible to derive formulae to estimate these forces from elementary mechanics of the rupture of ice. The basic formula may be written: F = ϕ(C)rced, where ϕ(C) is a function of the geometrical and physical parameters of the system, rc is the compression strength of the ice, e is the thickness of the ice, and d is the width of the structure. The paper deals with the different types of rupture patterns that may develop in front of either vertical or inclined faces, and formulae are given for some typical cases.
