​​​​What are Dampers? What is the purpose of Damper in Overhead Transmission wires?

 

Dampers used in transmission lines for avoiding oscillations in overhead transmission lines. 
Due to laminar wind, overhead transmission lines will be excited to vibrations and oscillations that can lead to damage on the conductor of the overhead transmission line, single parts or the pole. In order to reduce these vibrations and oscillations to an uncritical dimension, damping systems will have to be installed in the overhead transmission lines.

Dampers used in transmission lines are of different types such as Stockbridge dampers, Spacer dampers etc.

​​How does a Musical Water Fountain Works?

Image
A Musical Fountain, also known as a dancing fountain, is a type of animated fountain for entertainment purposes that creates an aesthetic design (including three-dimensional images). This is achieved by employing the effects of timed sound waves and timed light (including laser) against water particles.  Modern-day fountains employ a computer-controlled pneumatic arrangement, essentially a pressurized cylinder of water with the provision of an expulsion mechanism(like a piston) and a nozzle at the outlet that is programmed to squirt water with a specific force for a specific duration while the computer also manages the audio output. The circulation system is also modernized with the help of pressure sensors and pumps to maintain continuity.  Old school fountains used the principle of siphoning to maintain continuity where the water level was maintained slightly above the height of the canons that squirted water such that any drop in water level resulted in a siphoning suction ...

​​What is an Auxanometer? How does it Work?

Image
An auxanometer is an apparatus for measuring increase or rate of growth in plants.  In case of an arc-auxanometer, there is a wire fixed with the plant apex on one end and a dead-weight on the other. It passes over a pulley which has a pointer attached to it.   When the plant's height increases, the pulley rotates and the pointer moves on a circular scale to directly give the magnitude of growth. The "rate of growth" is a derived measurement obtained by dividing the length of growth measured by the auxanometer, by the time said measurement took. Sensitive auxanometers allow measurement of growth as small as a micrometer, which allows measurement of growth in response to short-term changes in atmospheric composition. Auxanometers are used in the laboratory, the field, and the classroom. Koningsberger invented the auxanometer.

​​Why do we Hiccup?

Image
Hiccups can be annoying but they’re usually short-lived. However, some people may experience recurrent episodes of persistent hiccups. At its most basic, a hiccup is a reflex. It happens when a sudden contraction of your diaphragm causes the muscles of your chest and abdomen to shake. Then, the glottis, or the part of your throat where your vocal cords are located, closes.  This creates the noise of air expelled from your lungs or the “hic” sound that feels involuntary with hiccups. If you find yourself getting hiccups often, eating smaller meals and minimizing carbonated beverages and gassy foods might be helpful.
