A mechanical wave is created when a source of energy causes a vibration to travel through a medium
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
Light is not mechanical energy but it can be transformed into mechanical energy. Light creates an impact as it hits a surface.
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
They produce mechanical energy which then creates electricity
It creates sound energy as a side effect of its operation which is mechanical energy.
Both are same an mechanical design or engineer design creates a concept and then he build a design that output will be CAD data.
A mechanical sound wave is created when an object vibrates, causing the surrounding air molecules to also vibrate and transmit the sound energy through the air.
The electrical energy from the audio signal is transformed into mechanical energy as the speaker cones vibrate. This mechanical energy then creates sound waves in the surrounding air, which we perceive as sound.
The chemical energy in the battery creates electrical energy, which powers up the starter and the rest of the ignition electronics. The starter converts electrical energy into mechanical energy to spin the engine, and the electrical system creates thermal energy across the spark plug gaps (if you have spark plugs, which is most vehicles). This ignites the fuel-air mixture, and the burning of fuel is the change of chemical energy in the fuel into thermal energy. The thermal energy creates pressure in the combustion chamber, and this pressure increase is mechanical energy. That mechanical energy forces the piston down, and the mechanical energy is eventually transferred to the wheels to move the vehicle.
Rub your hands together and they feel warm, right? That's it, rubbing your hands is using mechanical energy, which is by friction then converted to thermal energy (heat).
An example of a mechanical wave is a sound wave traveling through the air. Sound waves require a medium, such as air, to transfer energy through compression and rarefaction of the molecules. The vibration of the air particles creates a mechanical disturbance that propagates as a sound wave.
Mechanical waves are caused by the vibration of particles in a medium, such as a solid, liquid, or gas. When a disturbance, such as a sound source or a force, is applied to the medium, it creates a ripple effect that travels through the medium as a wave.
