Object Details
- Description
- Manufacturers compiled and distributed tables for designers who would use their products. This 32-page pamphlet, published in August, 1931, by the Southwark Foundry and Machine Company Division of the Baldwin-Southwark Corporation, brought together data “of particular interest and value” to those “engaged in the use of hydraulic equipment - particularly those structures involving the use of hydraulic pressures for load-producing purposes.”
- Tables included give:
- 1. the circumferences and areas of circles of diameters ranging from 1/64” to 98.”
- 2. conversions between standard and metric units of length, area, volume, velocity, weight, pressure, and power.
- 3. the capacities of hydraulic rams
- 3. plunger displacements
- 4. wire and sheet metal gauges
- 5. properties of steel pipes and bolts
- 6. the specific gravity of diverse substances
- 7. strength of diverse materials
- 8. friction losses in fluid flow
- 9. properties of various cross sections of pipe
- 10. properties of diverse beams
- 11. methods of finding moments of inertia
- 12. trigonometric formulae
- 13. properties of springs
- 14. graphs for estimating the weights of solid and hollow cylinders.
