SET FOR STUDY OF LAWS OF MOTION

摘要

The set for study of laws of motion consisting of the body with the cover, a upright to have a vertical rod, a horizontal rod, a cross couplings, treads in the form of the elbow with applied by a linear scale on the external side of the elbow and an aperture on the other elbow flange in the end of scale area; a metal ball, metal springs with grip pawls on the ends; a dynamometer; pawl-weights, a friction block; a discharge vessel; weights; a set of irregularly shaped bodies; a stopwatch; a swing pool; a set of equal volume bodies; a glass tube with stoppers on the ends. The set is additionally provided for mud weight balance where a level, balance is included, an arrow and an axis, besides there is a graduated arc with alignment and indexing holes and applied laying of bevels, being dismountable on one side of the cover, for instance, forks connections and on the opposite side there are lock pins, corresponding detachable contact joint elements and lock pin are mounted on the butt end of side walls of the body where in the body cover there is a slot for the graduating arc, inside of the body there are fixed members for position of the graduating arc and on the second flange of the tread there is an aperture, a symmetric hole on the first flange. On the upper plane of the frontal wall of the body there are threaded cavities for installation of a mounting rod where on the right butt of the frontal body wall there is a threaded cavity for an additional cap screw, a discharge vessel made as a cylindrical transparent bowl, the inner volume being divided by a partition into cabinets of big and small volumes where the cabinets by a drain tube are connected and each of them has a measuring scale.
