Crushing Energy & Work of Crushing Machines

05/03/2016 Taking grading analyses showing the results of three crushing tests, he computes the relative mechanical efficiencies according to the method of volumes (Stadler’s method) and to the method of areas exposed by crushing. In applying this latter method Del Mar assumes the relative energy unit for each grade as the reciprocal of the average size of particle in the grade. The calculations

Rankin's Formula Example for Column Crushing/Buckling Load

06/12/2014 It is an empirical formula used for the calculation of ultimate load both for short and long columns. Rankin’s formula is also known as Rankin Gordon Formula. It gives the ultimate load that column can bear before failure. If column is short, calculated load will be known as crushing load. And load will be buckling or crippling load, in case of long column.
