APPARATUS YOUNG MODULUS SEARLE’S

Modulus of elasticity is a measure of stiffness of a given material. Specially designed apparatus capable of high sensitivity and accuracy. Two metal rectangular frames hinged together parallel to each other, to allow only vertical relative motion, with a spirit level fixed on a cross-bar pivoted across the frames for noting the reference point. One frame has a vertical scale with a micrometer head reading to 0.01mm. Each frame has a self-centering chuck at its top for holding wires, load hooks are at the bottom. Includes a ceiling bracket carrying a pair of chucks, a counterpoise weight and a set of two wires, one each of brass and steel.
