Mechanical presses apply high force to shape, cut, compress or extract materials. They range in size from small hand-operated units to large industrial presses. Different mechanisms generate force, and they are used for various applications such as punching, stamping, bending, and liquid extraction. The amount of force a press can generate is known as its […]
Mechanical bushings are used to reduce friction and wear between mechanical parts or limit movement. They consist of a rotating rod or shaft that slides through a bore lined with a bushing. Materials used include Babbitt metal, plastic, aluminum, rubber, bronze, carbon, and ceramics. They should not be confused with normal bearings. A mechanical bushing […]
Mechanical growth factor (MGF) is a type of growth factor that enters muscle fibers to repair skeletal muscle tissue and prevent damaged cell death. It is triggered by rigorous exercise and muscle damage and differs from insulin-like growth factor-1 (IGF-1) in its structure and release signals. MGF supplements have limited effectiveness for older people due […]
Mechanical floors in tall buildings house building systems such as climate control, electrical panels, and elevator controls. They are not accessible by normal elevators and may require special access. They can also be used for storage and high-security equipment. Integrating them into building design can be challenging. A mechanical floor is a floor in a […]
A mechanical room, also known as a boiler room or technical room, houses equipment used to control a building’s environment. Equipment varies based on building needs and codes, and design considerations include layout, drainage, ventilation, insulation, and safety features. A mechanical room is a room that houses a variety of mechanical equipment, especially equipment used […]
A mechanical superintendent oversees construction, maintenance, and repair of large mechanical equipment in industrial plants, buildings, and hospitals. They require knowledge of mechanical systems and leadership skills to direct maintenance crews and ensure efficient completion of projects. Education and hands-on experience are necessary for the job. A mechanical superintendent coordinates and supervises construction, maintenance, and […]
Mechanical alloying is a powder metalworking technique that crushes base materials into a fine powder form in a ball mill, followed by cold welding. This process creates designer superalloyed metals with desirable physical properties used in spacecraft and satellite equipment. Cold welding involves placing pre-alloy component powders together under extreme pressure of a vacuum and […]
Mechanical alloying is a powder metalworking technique that involves crushing base materials into a fine powder form in a ball mill, followed by cold welding under vacuum pressure. This process creates designer superalloyed metals with desirable physical properties, used in spacecraft and satellite equipment. The use of hot isostatic pressure aids in the creation of […]
Mechanical refrigeration uses a sealed circuit of tubes to circulate fluid, absorbing heat and releasing it elsewhere. The cycle relies on a compressor, condenser, metering device, and evaporator to reduce temperature. While not the most efficient or eco-friendly method, it remains the standard for cooling. Mechanical refrigeration is a method of removing heat from where […]
Mechanical patents allow inventors to retain exclusive rights to their new and useful inventions. A mechanical patent attorney can help with the application process, including completing an Invention Disclosure and conducting a patentability search. Once filed, the inventor receives “patent pending” status before a patent examiner reviews and approves the patent. Inventors or scientists who […]
Mechanical linkage uses rigid rods to operate devices, such as the throttle and gearbox in automobiles. It provides a greater level of control for the operator and can be designed with ball bearings for smoother operation. The operator can fine-tune the machine’s reaction by adjusting the linkage. It maintains human input and control in operating […]
Mechanical engineering can be learned online for degree completion, skill enhancement, or personal interest. Online schools offer limited services, while traditional universities provide access to a wide range of student services. Minimum academic credentials are required, and transfer credits may be available. Free courses are available online, and graduate programs and certificates are available for […]
To earn a PhD in mechanical engineering, one must first be accepted into a doctoral program, which requires a high GPA, letters of recommendation, and an interview. Starting at the undergraduate level is recommended. A master’s program requires innovation and hard work, and a thesis is recommended for those who want to pursue a doctorate. […]
The mechanical aptitude test measures basic ability and understanding of mechanics and machines, and can be used in various fields. It also assesses interest in the field and covers topics such as how mechanical items work and principles of electricity. Employers may use it during the interview process, and it can also be taken for […]
Mechanical waves are disturbances that move through a medium, such as sound in air or seismic waves in rock. There are three types: transverse, longitudinal, and boundary. Waves have characteristics of frequency, period, wavelength, and amplitude. Transverse waves move up-and-down or side-to-side, longitudinal waves move through the expansion and compression of particles, and boundary waves […]
Mechanical engineering interviews test a candidate’s understanding of physical principles, problem-solving, personality, and work style. Positive and negative questions are asked to assess the candidate’s achievements and how they handle adversity. Technical questions are also asked to determine their understanding of mechanical engineering. Personal questions are asked to see if the candidate’s personality is a […]
Mechanical splicing permanently joins two fibers in a fiber optic cable, providing a fast and effective way to transmit data. It involves stripping the protective sheath, cutting the fibers with a cleaver, and using an alignment tool. There are four types of alignment tools, including capillary tubes and V-groove tools. Mechanical splicing is quicker and […]
An entry-level mechanical engineer is a recent graduate with a bachelor’s or master’s degree in mechanical engineering and no work experience. They have received training and may have hands-on experience through internships. Companies offer entry-level positions and promotions over time, and mechanical engineers can work in various industries. A resume should highlight training, honors, special […]
Professional mechanical engineers design and build machines for manufacturing plants, buildings, and homes. They specialize in fields such as aeronautics, automobiles, industrial equipment, robotics, or consumer electronics. They conduct extensive research, create computer models and blueprints, and build physical prototypes. They work with a team to test and make fine adjustments to ensure proper functioning. […]
Junior mechanical engineers work in research and development divisions of manufacturing companies, designing, building, and testing machines and equipment. They specialize in fields such as biotechnology, industrial machinery design, and automobile manufacturing. They create blueprints, write technical documents, and analyze statistics. A bachelor’s degree and formal training are required, and certification exams can enhance credentials. […]
