Abstract:

Instrumentation has been developed for measuring frictional forces at high velocities between rock samples and the outer rim of a rotating steel wheel. The instrumentation has been used to determine sliding friction values for volcanic tuff, wet and dry sandstone, limestone, grout, bronze and teflon.
