Engineering technicians help scientists and engineers solve technical problems.
Engineering technicians solve technical problems in a variety of areas. Their duties are more practical and limited in scope than those of scientists and engineers. Many help scientists in research and development. Others assist engineers in production and inspection. Technicians follow engineering standards and methods and procedures set by supervisors. They take samples, collect data, perform tests, and calculate results. They also inspect projects or products. Technicians may prepare drawings, research documents and records, and help write reports.
Engineering technologists handle the technical side of making a product. They prepare drawings and write reports. They also supervise the work of technicians and craftworkers, and oversee manufacturing or construction activities. Technologists who work for manufacturers may develop new products. They solve production problems. They must also test products for quality.
Most engineering technicians and technologists use computers and do computer-aided design. They may do basic computer programming.
Most of the engineering specialties employ technicians and technologists. Chemical engineering technicians design, install, test, monitor, and adjust equipment. They work in industries that make drugs, chemicals, and petroleum products. Civil engineering technicians help engineers plan and build roadways and structures. They also inspect water and wastewater treatment systems. Electronic engineering technicians design, develop, repair, manufacture, test, and adjust equipment. This equipment includes radios, radar, sonar, television, industrial and medical measuring or control devices, navigational equipment, and computers. Industrial engineering technicians study, plan, and analyze production costs of personnel, materials, and machines. They work in factories, stores, repair shops, and offices. Mechanical engineering technicians help design, develop, test, inspect, and manufacture machinery and industrial robotics.
Engineering Technicians is in the Engineering, Science, and Technologies Career Cluster.
Worker Characteristics
• Good ability to look at a drawing and mentally visualize what the finished object will look like
• Good ability to see details in pictures and blueprints
• Good ability to understand and use words when talking or writing
• Good ability to work with numbers
• Ability to gather details from spoken or written material
• Ability to coordinate the movement of eyes and hands while assembling products
• Ability to make decisions and solve problems
• Ability to move the fingers rapidly while attaching parts
• Ability to move the hands easily and skillfully while working on products
• Ability to create a product that meets certain levels of performance
Engineering technicians should be creative in design work. The ability to work well with others is important.
Physical Demands
• Frequently need to see nearby objects clearly, such as different screws
• Frequently use arms and hands reach for and handle objects, such as screwdrivers
• Frequently use fingers to pick up small items, such as nuts and bolts
• Frequently lift and move objects that weigh up to ten pounds
• Occasionally lift and move objects that weigh up to 20 pounds
• Occasionally climb, balance, kneel, and crouch while working
• Occasionally judge the distance between objects
• Occasionally use touch to determine whether two parts are put together correctly
• Occasionally talk and listen to others
• Occasionally need to tell the difference between colors
• Occasionally need to see distant objects clearly
Work Setting
Engineering technicians usually work indoors. They may do some outdoor inspections and surveys. Most engineering technicians work regular hours in offices, laboratories, electronics shops, industrial plants, or construction sites. Construction sites may be noisy and wet. They are cold in winter and hot in summer. Engineering technicians are occasionally exposed to the weather. They may sometimes be exposed to electrical shock. They work as part of a team, responding to directions of engineers and scientists. They also work independently, drawing conclusions based on observations and tests. Long hours are common when doing fieldwork. Some travel to customers' businesses. Hazards include exposure to electrical shock, eyestrain from computer use, and exposure to fumes and chemicals. Many belong to the American Society of Certified Engineering Technicians.

uso del diccionario bilingue
El diccionario bilingüe es aquel que ofrece dos listas alfabéticas de términos, una en cada uno de los idiomas de los que se ocupa, y traduce los significados. Adicionalmente se utiliza para conocer el uso de la palabra y su ortografía, así como su función gramatical.
El diccionario bilingüe está dividido en dos partes, la primera contiene las palabras en un idioma y a continuación su significado en el otro (español – inglés). En la segunda parte, los idiomas se invierten (inglés – español). Algunos presentan listas de verbos, vocabulario o gramática. Son muy útiles los diccionarios que tienen la pronunciación. Ésta consiste en la trascripción al español de los sonidos de la palabra que requieres en inglés y viceversa. El diccionario también te indica la función gramatical de la palabra que buscas, es decir, si es sustantivo, verbo, adjetivo o adverbio. No ignores esa información. No te conformes con la primera definición del diccionario, estudia todas las definiciones y elije la más adecuada a cada situación o contexto.
ELEMENTOS DEL DICCIONARIO BILINGÜE
En primer lugar, aparece la palabra que buscas en negritas, es decir, la entrada. Luego, algunos diccionarios indican la pronunciación de esa entrada, y además, las abreviaturas que señalan la función que cumple esa palabra en la oración. Esta función se refiere a la categoría gramatical, como lo es el nombre, el verbo, el adjetivo, la preposición, el artículo. En inglés, las palabras pueden pertenecer a distintas categorías gramaticales de acuerdo a la posición que ocupan en la oración. Es así como la palabra arm, por ejemplo, en inglés tiene distintos significados porque cumple diferentes funciones gramaticales, como puede observarse en el siguiente cuadro
arm [αrm] s. (anatomy) brazo; (weapon) arma; - in - de bracete, de bracero, Ríopl.,
Cuba de brazo, de brazos; at -‘s length
a una brazada; with open -s con los
brazos abiertos; v. armar(se).

Roman cement: Concrete has been used as a construction material for centuries. Before 100 B.C. the Romans had developed an excellent concrete which enabled them to erect vast structures and works of engineering.
On the slopes of Mt. Vesuvius and in extinct volcanic areas near Rome they found a light, porous volcanic rock. Its rough surface formed a good bond for cementitious material (a substance capable of acting as a cement), or mortar. The cement was prepared from a mixture of lime and a volcanic ash called pozzolana, named after the village of Pozzuoli near Mt. Vesuvius . When the pozzolana was mixed with limestone and burned, the resulting material, ground and mixed with water, gave a cement of unprecedented strength. Roman cement was a hydraulic cement, one that will harden under water. This cement, mixed with small pieces of volcanic rock, formed a lasting concrete.
As the Roman Empire expanded the knowledge of concrete spread throughout Europe and Asia . The quality of the concrete had to be determined by extensive trial and error. It varied from area to area, depending on the purity and composition of the available raw materials.
