It represents a specification to be designed to rather than as a result of design and the mean piston velocity is a function of the revolutions per minute, that is, the piston at a specific rpm is going to be the same at the peak of the graph as it is at the trough, that is at 286.071 degrees on the crankshaft if the rpm is held consistent.
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. [1] The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common.
A drawing design of the N&W class J locomotive. After the outbreak of World War II, the Norfolk and Western Railway's (N&W) mechanical engineering team developed a new locomotive—the streamlined class J 4-8-4 Northern—to handle rising mainline passenger traffic over the Blue Ridge Mountains, especially on steep grades in Virginia and West Virginia.
25 meter pistol, formerly and unofficially still often known as sport pistol, is one of the ISSF shooting events. It was devised as a women's event in the 1960s, based upon the rules of 25 meter center-fire pistol but shot with a .22-caliber sport pistol instead of the larger-caliber guns men used.
The target: total Ø = 154.4 mm. 4 ring Ø = 106.4 mm. 9 ring Ø = 26.4 mm. 10 ring Ø = 10.4 mm, height 0.75 m above the floor. 50 meter rifle prone (formerly known as one of four free rifle disciplines) is an International Shooting Sport Federation event consisting of 60 shots from the prone position with a .22 Long Rifle (5.6 mm) caliber rifle.
50 meter rifle three positions (formerly known as one of four free rifle disciplines) is an International Shooting Sport Federation event, a miniature version of 300 meter rifle three positions. It consists of the kneeling , prone , and standing positions, fired in that order, traditionally with 3×40 shots for men and 3×20 shots for women.
