Measure the length of a curve by treating the curve as part of a complete circle. Once the diameter of the circle is known, it is possible to calculate the length of the curve.
Continue ReadingUse a straightedge tool to extend a line from either edge of the curve towards the center. Where these two lines meet is the radius of the circle. Multiply the radius by 2 to get the diameter.
Center a protractor in the middle of the circle so that the zero edge overlays the diameter line. Align the rotating edge of the protractor with the top of the curve. This is the angle of the curve.
Multiply the diameter by pi, and then multiply the solution by the angle. The result is the length of the curve.
The length of an arc of a circle is equal to the angle subtended by the arc, in radians, times the radius of the circle. For an angle measured in degrees, the arc length is the angle, in degrees, times the radius times pi divided by 180.
Full Answer >Measure the length of a bolt from the underside of the bolt head to the end of the shank, and to measure diameter, measure the widest part of the shank of the bolt. Length and diameter can be measured in millimeters or inches, and they are the two principal dimensions of a bolt.
Full Answer >A calibration curve is a mathematical tool used in analytical chemistry that provides a set of reference points that unknown chemical substances can be compared to. When analyzing certain substances, scientists are often unable to get a completely accurate understanding of the substance's makeup. With a calibration curve, chemists can compare known information about unknown substances to make estimates about its makeup and chemical properties
Full Answer >A tangent is a line that intersects a curve at only one point and does not pass through it, such that its slope is equal to the curve's slope at that point. To find a horizontal tangent, you must find a point at which the slope of a curve is zero, which takes about 10 minutes when using a calculator.
