In theory a pulley is simply a smooth body which changes the direction of a
flexible and inextensible cord stretched across part of its surface ; in practice ( to
escape as much as possible of the inevitable friction ) it is a wheel , on part of
whose ...

The intensity of heat and light emanating from a point , or from a uniformly
radiating spherical surface , diminishes according to the inverse square of the
distance from the centre . Hence the rate at which a planet receives heat and light
from ...

Consider a spherical surface within the body , with its centre at the fixed point C.
All points of this sphere attached to the body will move on a sphere fixed in space
. Hence the construction of 91 may be made , only with great circles instead of ...

This ( as all rolling of cones ) is exhibited best by taking the intersection of each
with a spherical surface . Thus we see that if a spherical polygon turns about its
angular points in succession , always keeping on the spherical surface , and if
the ...
