In some cases they are de facto leaders not occupying either of those positions or prime ministers who are not heads of government. They are heads of state and heads of government. Today, it’s still widely used by outdoor activity enthusiasts, military operations, and sailors.This page lists the national rulers in the world. The compass is known as one of the “Four Great Inventions” of China (alongside gunpowder, papermaking, and printing) and was initially used as a tool for divination. Used for navigation and establishing orientation, it relies on the natural magnetic pull of the Earth to establish a relative direction for the user. One of history’s most revered inventions, the compass was integral in kicking off the age of exploration in seafaring travel. Utilized in a wide variety of fields, calipers can be found in the offices of mechanical engineers, scientists, and doctors, as well as in the field with metalworkers, woodworkers, and forestry researchers. By adjusting the tips of the calipers to fit across the object to be measured and removing the calipers, the total distance can be measured via an integrated ruler. Over the course of treatment, this tool allows them to keep an objective record of the recovery process in cases of joint injuries.Īvailable in analog or digital measuring versions, calipers are an indispensable tool for measuring the distance between two opposite sides of an object. The bubble inclinometer is often used by sports therapists to test for a healthy range of motion at the body’s crucial junctures. To identify the range of motion of a joint to be measured, simply place the inclinometer directly next to it, turn the dial until the scale reads 0, take the joint through its range, and read the range from the inclinometer. While there are plenty of digital options for measuring angles, sometimes the assurance of an inexpensive all-weather tool wins out over pricier and more fickle technologies.ĭesigned specifically for measuring the range of motion at a joint, the bubble inclinometer can also be used to measure the steepness of a grade. Occasionally, you’ll also find models that include self-threading screws for use with nonmetallic measuring squares.Īllowing for easy measurements at a glance of angles from 0° to 90°, some angle locators also come with conversion guides that make them useful for identifying roof pitches, stair slopes, or drainage angles. Angle LocatorĪlso known as an angle finder, an angle locator features a magnetic base that can attach to metal measuring squares. The 14 Different Types of Measuring Tools Analog Measuring Tools 1. First, we’ll look at the different types of analog measuring tools and then examine the digital tools available. To help familiarize yourself with this portion of the working world, we’ve put together a list of these types of measuring tools, complete with examples of their real-world uses. More than that, measuring tools provide a surefire way to observe and record the world around us, so we can better pass on lessons to the next generation of students and professionals. Tools that can provide accurate measurements are an essential element of any trade profession, from carpentry to plumbing to stonemasonry.
