The sine wave is the curve that naturally occurs when the restoring force is proportional to the displacement. The math is a little complicated (the sine wave in this case is the solution of the corresponding differential equation), but the point is, this relationship between the force and the displacement is a fairly common situation.

Why is heat observed when current flows through the circuit?
The heat observed in a circuit is the result of electrical resistance.Under normal circumstances, every electrical circuit has a certain amount of resistance to the flow of electricity. Electronflow opposed by the physical nature of the conductor. This is the fundamental nature of electrical resistance. Whenever this happens, the energy of those electrons is absorbed by the conductor (as opposed to flowing through) which then emitts this captured energy as heat. The higher a conductor's resistance, the more electrical energy is converted to heat by it.
What are the 10 examples of non-electrical technology?
Oh, what a lovely question! Non-electrical technology is all around us, like bicycles, sewing machines, windmills, and even simple tools like hammers and nails. Nature itself provides us with amazing non-electrical technology, such as the design of a bird's nest or the structure of a spider's web. Just take a moment to appreciate the beauty and ingenuity of the world around you!
What does oscillate mean?
Oscillations are reoccurring and regular fluctuations between particular states within a system. These states could be discrete, such as a car's turn signal blinking on and off; continuous, such as a wave; damped, such as the gradual decay of the amplitude of a vibrating guitar string; or driven, such as the forced motion of someone on a swing. The states involved in an oscillation don't have to just be mechanical in nature. For example, the stock market oscillates between a bull and a bear market, or your favorite style of music may oscillate between jazz and blues. Even driving to and from work everyday along the same route at the same time is an oscillation. The key things to remember are that oscillations require a "back and forth" motion, and that this motion must happen again and again and again. Thus, bouncing a basketball off the ground and then catching it isn't an oscillation, because the "back and forth" motion only happens once. Additionally, the Earth's orbit around the Sun isn't an oscillation, because, while it does indeed happen over and over again, the motion isn't "back and forth."
Is mechanical engineering easy?
Bull hocky easy! If you want to plan a job and make a bit more you have to know how to add. The test is: You have to start wiring a home from the main panel plans and add six inches at an outlet box. You measure to the next box and so on to the last box in that circuit then go back to the panel and start on the next line of outlets. How much wire do you need?
What is a servo valve?
A servomechanism, usually shortened to just servo, is a device used to provide mechanical control at a distance. For example, a servo can be used at a remote location to proportionally follow the angular position of a control knob. The connection between the two is not mechanical, but electrical or wireless, for example. The most common type of servo is that mentioned, which gives positional control. Servos are commonly electrical or partially electronic in nature, using an electric motor as the primary means of creating mechanical force, though other types that use hydraulics, pneumatics or magnetic principles are available. Usually, servos operate on the principle of negative feedback, where the control input is compared to the actual position of the mechanical system as measured by some sort of transducer at the output. Any difference between the actual and wanted values (an "error signal") is amplified and used to drive the system in the direction necessary to reduce or eliminate the error. A whole science of this type of system has been developed, known as control theory. Servos are found in many applications. They operate the throttle of engines that use a cruise control. CNC machines use servos to make the motion axes of a machine tool follow the desired tool path. Fly-by-wire systems in aircraft use servos to actuate the control surfaces that control the aircraft. Radio-controlled airplanes use servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the focus.
