Abstract

Presents a procedure which, through the use of nomographs, permits rapid estimation of the force required to crosscut shear logs of various species and diameters with shear blades ranging in thickness from 1/4 to 7/8 inch. In addition, nomographs are included to evaluate hydraulic cylinder sizes, pump capacities, and motor horsepower requirements to effect the cut.

Keywords

shearing force, horsepower, cylinder sizes, pump capacity, nomographs, shear blade thickness
