विस्तृत सूचना

The RBF-200 is a compact, bench-mounted machine designed to apply reversed bending loads to unthreaded, straight shank specimen bars.

Specimen design

The applicable inch-pound moment setting for the poise weight is determined on the basis of some desired bending stress level in the specimen. Generally, this moment may be determined from the equation: 

M = SD3/32 = 0.0982 SD3

Where,        M = Setting for poise weight in inch-pounds 

                        S = Desired bending stress level in specimen at minimum cross section in pounds per square inch 

D = Diameter of specimen at minimum cross section in inches.
