Force Calibrations in the Nanonewton Regime

January 1, 1994
Author(s)
Lowell P. Howard, E C. Teague
An instrument is described which is shown capable of making preliminary measurements of nanonewton forces. A technique is described which allows absolute calibrations of small forces to be made in terms of electrical measurements.

Heat Flux From Flames to Vertical Surfaces

January 1, 1994
Author(s)
J. G. Quintiere, Thomas Cleary
Dimensional analysis is used to examine heat transfer from flames to vertical surfaces. Configurations include a line fire against a wall, a square burner flame against a wall and in a corner, and window flames impinging on a wall. Dimensionless parameters

Hertzian Contact Resonances

January 1, 1994
Author(s)
John A. Kramar, T Mcwaid, J Schneir, E C. Teague
The resonant frequency of a sphere in contact with a flat surface was measured as a function of loading force for contacting materials with different elastic moduli. Comparisons were made with predictions based on the Hertzian theory of elastic deformation
