Manufacturing Inventory: It is the inventory held for manufacturing and selling of goods. Based on the value addition or stage of completion, the manufacturing inventories are further classified into 3 types of inventory â Raw Material, Work-In-Progress and Finished Goods. Another type is MRO inventories which are to support the whole manufacturing and administrating operation.
Principle of the Lever. It has been found by experiment that two equal forces acting in opposite directions, i.e., clockwise and counterclockwise, and applied to a uniform lever at equal distances from the fulcrum counteract each other and establish a state of equilibriumequilibrium, state of balance.
A lever, one of the six simple machines.copyrightCopyright Â© U.S. Department of Transportation, Federal Highway Administration, http://www.fhwa.dot.gov/environment/fspubs/05232810/page16.htm. Students are introduced to three of the six simple machines used by many engineers: lever, pulley, and wheel-and-axle. In general, engineers use the lever to magnify the force applied to an object, the pulley to lift heavy loads over a vertical path, and the wheel-and-axle to magnify the torque applied to an object. The mechanical advantage of these machines helps determine their ability to make work easier or make work faster.
