STEEL SPRINGS.
(Hamilton.) . -

Rule 1st—To find elasticity of a given steel-plate spring; Breadth of plate in inches multiplied by cube of the thickness in 3% inch, and by mumber of plates; divide cube of span in inches by prod ct so found, and multiply by 1.66. Result, equal elasticity in }{4 of an inch per ton of load. .. Rule 2d—To find span due to a given elasticity, and number and size of plate ; Multiply elasticity in sixteenths per ton, by breadth of plate in inches, and divide by cube of the thickness in inches, and by the number of plates; divide by 1.66 and find cube root of the quotient. Result, equal span in inches. Rule 3d—To find number of plates due to a given elasticity, span and size of plates: Multiply the cube of the span in inches by 1.66; multiply the elasticity in sixteenths by the breadth of the plate in inches, and by the cube of the thickness in sixteenths; divide the former product by the latter. The quotient is the number of plates. . Rule 4th–To find working strength of a given steel-plate spring: Multiply the breadth of plate in inches by the square of the thickness in sixteenths, and by the number of plates; multiply also the working span in inches by 11.3; divide the former product by the latter. Result, equal working strength in tons burden. Rule 5th–To find span due to a given strength and number, and size of plate ; Multiply the breadth of plate in inches by the square of the thickness in sixteenths, and by the number of plates ; multiply, also, the strength in tons by 11.3; divide the former product by the latter. Result equal working span in inches. Rule 6th–To find the number of plates due to a given strength, span and size of plate: Multiply the strength in tons by span in inches, and divide by 11.3; multiply also the breadth of plate in inches by the square of the thickness in sixteenths; divide the former product by the latter. Result, equal number of plates. The span is that due to the form of the spring loaded. Extra thick plates must be replaced by an equivalent number of plates of the ruling thickness, before applying the rule. To find this, multiply the number of extra plates by the square of their thickness, and divide by the square of the ruling thickness; conversely, the number of plates of the ruling thickness to be removed for a given number of extra plates, may be found in the same Way.
