摘要:

The thermal stress in thin-walled cylinders of any cross section has been investigated for internal and external temperatures each varying in any manner round the circumference but not in the axial direction. The thickness also may vary round the circumference.A method is given for calculating the stress from given temperature distributions, whatever the shape of the cross section. The stress is evaluated for uniform, but different, inside and outside temperatures.The circular cylinder is treated in detail and the stress found for the general case of circumferential variation. It is shown that the maximum stress will depend only on the temperature distributions and the material, and not on the thickness or diameter of the cylinder.

摘要:

An all-metal adiabatic vacuum calorimeter was used to determine the specific heat of copper over small temperature intervals from 30° to 200° K. The accuracy is considered to be within 0.05% for the greater part of the range. A curve is given showing the variation with temperature of the characteristic temperature, θ, for copper.
