🤔 How it works …….. ⁉
How a weight machine works
Scales people use to weigh themselves often work this way. You stand on a platform and your weight, pushing down, compresses a pressure sensor called a piezoelectric transducer. This is a kind of crystal that makes an electric current when you squeeze it: the harder you push, the more current it makes.
Digital scales use “a “. A system of levers translates your weight standing on a scale into a bending force on a calibrated metal block, and the strain gauge measures how much it bends, producing a voltage proportional to the force.
There may be two or even four strain gauges that measure the difference in strain between the two sides, to compensate for temperature dependence (the resistance of the gauge can change with temperature as well as with strain).
The voltage is converted to numbers in an , Analog to digital convertor. manipulated in a small dedicated computer to set the zero and scale, and displayed on an LCD display.
😳Why❓❓❓
Why should one not sleep under the trees at night.
During the day, in presence of sunlight, the plants use up the CO2 and release O2 in the process of photosynthesis. But during night, plants won’t perform photosynthesis so they are unable to use the CO2 and this further leads to increase in the proportion of CO2 in the air.
During night the trees breathe in oxygen and release CO2. If one sleeps under the trees, the amount of increased CO2 in the air around will certainly affect the health. So it is inadvisable to sleep under trees during night.
