SS Myron agreement with the GLSHS, an axe, double sheave block, signs, a valve, steering wheel, steam whistle, lumber hook, open-end wrenches, a soup bowl, an oiler, and a block pulley from "Myron" are now the property of the State of Michigan. "Myron"s artifacts are on loan to the GLSHS for display in the Great Lakes Shipwreck Museum. "Myron"s remains are shattered by surf and ice but she is a popular site for scuba divers. Her bow sits upright draped with anchor chains. A large windlass lies just off her bow. The boiler and engine sit off her port side, a metal
Block and tackle more precise estimate of efficiency is possible by use of the sheave friction factor, formula_12 (which may be obtainable from the manufacturer or published tables). The relevant equation is: Typical formula_12 values are 1.04 for roller bearing sheaves and 1.09 for plain bearing sheaves (with wire rope). The increased force produced by a tackle is offset by both the increased length of rope needed and the friction in the system. In order to raise a block and tackle with a mechanical advantage of 6 a distance of 1 metre, it is necessary to pull 6 metres of rope through the
