ON THE CONSTRUCTION AND APPLICATION OF FORMULAE FOR THE TRANSVERSE STRENGTH OF SOLID RECTANGULAR BEAMS.-VII

BUT it is the deficiency in stiffness that is usually measured, and this is represented by the amount of deflection produced by a given weight, and the law for comparative deflection in the converse of that for comparative stiffness, and including the weight is as follows:-the deflection is as the weight and the cube of the length directly, and as the breadth and the cube of the depth inversely.
