How does one-way clutch work?
The one-way clutch is a functional component located between cylindrical inner and outer rings for transmitting or suspending torque, which transmits torque in one rotational direction while stopping torque transmission in the opposite direction.
What is the principle behind working of LED?
An LED bulb produces light by passing the electric current through a semiconducting material—the diode—which then emits photons (light) through the principle of electroluminescence. Don’t let that big word scare you! It essentially means that a material (in this case, the diode) casts light when power is applied to it.
How do you emit light?
Atoms emit light when they are heated or excited at high energy levels. The color of light that is emitted by an atom depends on how much energy the electron releases as it moves down different energy levels.
Who invented LED Malayali?
M A Johnson, an unschooled 49-year-old man, from Peruvannamuzhi, a sleepy hilly hamlet in Kozhikode district, is known to be a pioneer in the manufacture of LED (Light Emitting Diodes) bulbs in the country.

How does a 1 way bearing work?
One Way Bearings are designed to transmit torque between the shaft and housing in one direction and allow free motion in the opposite direction. Proper mounting is easily accomplished with a simple press fit in the housing. Clutches and clutch and bearing assemblies are offered both in inch and metric series.
