A rating that indicates the amount of electrical energy a battery can supply. The ampere-hour rating is the product of the current flow in amperes, multiplied by the length of time, in hours, the battery can supply this current. A 35-ampere-hour battery can supply seven amperes of current for five hours, or one ampere for 35 hours.

A rating used for aircraft and automobile tires to indicate their relative strength. The ply rating does not indicate the actual number of plies of fabric in the tire; rather, it indicates the number of plies of cotton fabric needed to produce the same strength as the actual plies.

A reciprocating engine in which all the cylinders are arranged in a straight line. In an in-line engine, the piston in each cylinder is connected to a separate throw of the crankshaft.
V-engines are a form of inline engine having two banks of cylinders mounted on the crankcase, with an angle of between 45 and 90 degrees between the banks. Two pistons, one in a cylinder in each bank, connect to each throw of the crankshaft.
Industry:Aviation
A reciprocating engine in which the camshaft is located in the cylinder head. The valves are opened by rocker arms that are actuated by the cam lobes. The valves of engines that have the camshaft in the crankcase are actuated by pushrods and rocker arms.
Industry:Aviation
A reciprocating engine in which the cylinders are arranged in two banks separated by 180°, with the cylinders and crankcase mounted in the aircraft so they are flat. The cylinders are staggered, with one bank slightly ahead of the other. Staggering the cylinders allows each piston to be connected to a separate throw of the crankshaft. Horizontally opposed engines are called flat engines.
