The FC Bond Mill was designed by F. C. Bond for use in determining the Bond Index, a measure of grindability and power required for grinding applications. The FC Bond Mills are used in laboratories throughout the world. A copy of Fred C. Bond's Method of Crushing and Grinding for determination of the Bond Index is included with each mill.

Both of the old theories have been remarkably barren of practical results when applied to actual crushing and grinding installations. The need for a new satisfactory theory is more acute than those not directly concerned with crushing and grinding calculations can realize.
Calculate the values of mean return and variance for the stock fund. (Do not round intermediate calculations. Round "Mean return" value to 1 decimal place and "Variance" to 4 decimal places.) Mean return Variance Calculate the value of the covariance between the stock and bond funds. Negative value should be indicated by a minus sign.
A Southern Pine sill plate has a Fc perp of 565 psi. This often controls post and stud design. Plywood has something like 350 psi for Fc perp. Designing around the plywood limits stud and post capacity greatly. In my experience, I ignore the plywood crushing. If you read the footnotes, the crushing limit is something like 5% deformation.
