The answer is a Telescopic gauge.
A Telescopic gauge is a tow point transfer gauge that can be used with an outside micrometre to measure inside diameter.
What is Telescopic gauge?
- Telescoping gauges are indirect measuring devices used to determine the internal diameter of a bore, hole, groove, slot, or other similar structure.
- A handle, two telescopic rods, and a locking screw make up this T-shaped tool.
- Telescopic gauges with two plunging telescopic rods are available, as are those with only one.
- Telescopic gauges are used to measure the internal diameter of a bore, hole, or groove with a diameter of up to 150mm (6′′), such as camshaft bearings or connecting rod bore bearings. They are primarily used by mechanics to measure the bore size of a crankcase in an engine with moving pistons.

In astronomy, Johannes Kepler published his three laws about planetary motion. It is one of the most important things in astronomy. So Kepler gives three laws about planetary motion.
<h3>What is motion?</h3>
Motion is a physical term in physics. If a particle of mass m and affected by some force F then it change its position in many different way. That is the motion of the object. It is a vector quantity.
<h3>What is Kepler's three laws?</h3>
In astronomy, Johannes Kepler published his three laws about planetary motion between 1609 and 1619. This shows about motion describe the orbits of planets around the Sun. So the three motions are shown following,
<u>First law</u>: Every planet in solar system that moves in a elliptical orbits where the sun always in the center of the motion.
<u>Second law</u>: Every planet covers the same amount of distance in a constant time no matter where the orbit of the planet placed. That means the velocity of every planet is not same. It varies along with the orbit. But every time the change of area is constant.
<u>Third law</u>: The orbital period of the planet is proportional with the cube of the semi major axis of the planet. It can be shown mathematically,
p²∝a³
Where we know,
p= The orbital period of the planet.
a= the semi major axis of the planet.
From the discussion we can easily shown that there are three laws of Kepler about planetary motion.
