Mid-parental height (MPH) is often used to predict the target height of an individual based on the heights of the two biological parents. It can be used to calculate the target height (TH) for children. MPH is given by (mother’s height + father’s height) divided by 2. MPH is unisex. Boys need an upward correction, girls need a downward ...
A height gauge is a measuring device used for determining the height of objects, and for marking of items to be worked on. [ 1 ] These measuring tools are used in metalworking or metrology to either set or measure vertical distances; [ citation needed ] the pointer is sharpened to allow it to act as a scriber and assist in marking out work pieces.
ANOVA gauge repeatability and reproducibility is a measurement systems analysis technique that uses an analysis of variance (ANOVA) random effects model to assess a measurement system. The evaluation of a measurement system is not limited to gauge but to all types of measuring instruments , test methods , and other measurement systems.
Gauge blocks (also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks) are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge blocks come in sets of blocks with a range of standard lengths.
Dial indicator, also known as a dial test indicator, dial gauge, or probe indicator an instrument used to accurately measure small linear distances. Feeler gauge: a simple tool used to measure gap widths. Gauge block, (also known as a gage block, Johansson gauge, slip gauge, or Jo block) a precision ground and lapped length measuring standard.
A variation is the snap indicator gauge, [7] which incorporates a dial indicator or electronic digital indicator as one of the anvils. This indicator displays the deviation from the preset dimension and the indicator may have high and low tolerance limits marked by means of two extra needles, alteration of the dial face, or programming into an ...
If the gauge block is known to be 0.75000 ± 0.00005 inch ("seven-fifty plus or minus fifty millionths", that is, "seven hundred fifty thou plus or minus half a tenth"), then the micrometer should measure it as 0.7500 inch. If the micrometer measures 0.7503 inch, then it is out of calibration.
Visual Glide Slope Indicator or Visual Glideslope Indicator (VGSI) is a ground device that uses lights to assist a pilot in landing an airplane at an airport. The lights define a vertical approach path during the final approach to a runway and can help the pilot determine if the airplane is too high or too low for an optimum landing.
