Inside small jaws: used to measure the internal diameter of an object (like a hollow cylinder or pipe). Depth probe, or depth rod: used to measure depths of an object (like a small beaker) or a hole. Main scale (metric): marked every millimeter and helps to measure length correct up to 1 mm. Main scale (imperial): marked in inches and fractions.
A variety of rulers A carpenter's rule Retractable flexible rule or tape measure A closeup of a steel ruler A ruler in combination with a letter scale. A ruler, sometimes called a rule, scale or a line gauge or metre/meter stick, is an instrument used to make length measurements, whereby a length is read from a series of markings called "rules" along an edge of the device.

This was a simple mechanical device that could measure a projectile's velocity. Robins reported muzzle velocities ranging from 1,400 ft/s (427 m/s) to 1,700 ft/s (518 m/s). In his book published that same year "New Principles of Gunnery", he uses numerical integration from Euler's method and found that air resistance varies as the square of the ...

868 m/s (2,848 ft/s) (Bullet velocities are highly variable as this metric is dependent on bullet weight and both the powder used and the weight of the powder charge. The velocity shown above is only a representative sample measurement.) Effective firing range: 1,000 m (1,094 yd) Maximum firing range: 1000 meters: Feed system
