A heat pump is a mechanical device that transfers heat from one environmental compartment to another, typically against a temperature gradient (i.e. from cool to hot). In order to do this, an energy input is required: this may be mechanical, electrical or thermal energy. In most modern ...
In a traditionalbrushedmotor, there are physical points of contact, called brushes, that connect the rotor to the stator. The stator passes electrical current to the rotor via the brushes, where it is converted into mechanical energy. Brushes generate heat, friction, and noise and they wear dow...
Mechanical engineering is a branch of engineering concerned with designing, producing and operating machinery, ranging from ranging from relatively simple items to more complex machinery and even entire facilities and plants.
The crankshaft thenturnsthe car’s drive wheels. Through this mechanism, explosive energy is turned into mechanical energy. So, where does the transmission come into play? In a vacuum (without a transmission), the explosive power produced by a typical automobile’s internal combustion engine would...
Environmental impact.The data centers and network infrastructures that underpin the operations of AI models consume large amounts of energy and water. Consequently, training and running AI models has asignificant impact on the climate. AI's carbon footprint is especially concerning for large generative...
While a heat sink can help reduce the overall noise level of a computer, it cannot eliminate all sources of noise. Heat sinks primarily focus on cooling the components, but other components, such as fans or mechanical hard drives, can still contribute to the overall noise level. However, by...

An 8.8 kg object is falling from a height of 1.9 m at 1.57 m/s. What is the total energy of the object? A satellite of mass m is in a circular earth orbit of radius r. (a) Give an algebraic expression for the satellite's mechanical energy in terms of the mass of th...
IoT is a system of connected devices, mechanical and digital machines, or objects with unique identifiers with the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. Athingin IoT can be a person's heart monitor implant, an automobile with...
What Is a Mechanical Engineering Major? Mechanical engineering majors learn about motion and energy, and they study fluid, solid and thermal mechanics. They spend time in labs, where they develop problem-solving skills and evaluate and design products. These products can range from prosthetics to ...
