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 output force), formula_5 is the ideal mechanical advantage of the system (which is the same as the number of segments of line extending from the moving block), and formula_6 is the mechanical efficiency of the system (equal to one for an ideal frictionless system; a fraction less than one for real-world systems with energy losses due to friction and other causes). If formula_7 is the number of sheaves in the purchase, and there is a roughly formula_8% loss of efficiency at each sheave due to friction, then: This approximation is more accurate for smaller values of formula_7 and formula_8.
