🤔 How it works …….. ⁉
Drones use their rotors—which consist of a propeller attached to a motor—to hover, meaning the downward thrust of the drone is equal to the gravitational pull working against it; climb, when pilots increase the speed until the rotors produce an upward force greater than gravity;
Propellers and engines give drones forward movement capabilities. In fixed-wing drones, the propeller provides forward propulsion, allowing the wing to generate lift.
On rotary-winged crafts like quadcopters, propellers provide lift as well as steering capabilities by generating downward and lateral forces.
Multi-Rotor works on relative nature of force, that means when the rotor pushes the air, the air also pushes the rotor back. This is the basic principle that the Multi-Rotor can go up and down. Furthermore, the faster the rotor rotates, the greater the lift, and vice versa.
😳Why❓❓❓
Why do people become mad?
Everyone of us oscillates between positive and negative emotions. Sometimes we go into the regions which are supposed to be “mad-regions”, but we are smart enough to come back to “normalcy” within reasonable time, or to fake normalcy.
Those who go mad, lose themselves in those regions (which are considered to be outside normal or sensible behavior), or they don’t consider returning to normalcy important enough or worth it, or the trigger (it may be one event or a series of events) after which they plunged into “madness” affected and moved them so strongly or the emotions (like guilt or rage or chronic depression or hopelessness or absurdity of deemed hypocrisy of “normal” people that their priorities and view of life is distorted.
They begin to disregard importance of living positive and constructive life and the fact that most people have to face their own problems. Perhaps madness may be caused by chemical imbalance in brain.

Did you know:
Banana is loaded with fibre, both soluble and insoluble. The soluble fiber has the tendency to slow down digestion and keep you feeling full for a longer time. Which is why bananas are often included in a breakfast meal so that you can start about your day without having to worry about the next meal
According to Ayurveda, banana has a sweet and sour taste. The sweet taste is said to bring about a sense of heaviness but the sour taste is known to stimulate agni (the digestive juices), thereby supporting digestion and helping in building up metabolism.
