INTRODUCTION TO ENGINEERING:
MECHANICAL ENGINEERING
QUESTIONS AND VERIFIED
ANSWERS|100% CORRECT|GRADE A+
mechanical engineering - ANSWER the designing, building, and maintenance of mechanical and fluid
systems
Often within their specialties, engineers will select a role that focuses on one of the followign aspects: -
ANSWER research, design, manufacturing, repair, or management
What classes? - ANSWER fundamentals of engineering, statics, dynamics, robotics, mechanics,
thermodynamics, calculus, and physics
Mechanical engineering technician - ANSWER -under the direction of an engineer
-assist engineers by completing drawings and models and by conducting research and tests
force - ANSWER push or pull on an object resulting from contact with another object
work - ANSWER the application of force to move an object a distance
power - ANSWER the rate at which work is performed or energy is transmitted
energy - ANSWER the ability to do work
potential energy - ANSWER energy that is stored and waiting to be used
kinetic energy - ANSWER energy in motion
mechanical energy - ANSWER energy in motion that uses mechanical devices for conversion
, ex of mechanical device - ANSWER levers, wheels. gears, pistons, internal combustion engine
power systems - ANSWER take energy and convert it into power to accomplish work (electrical, fluid,
mechanical)
Mechanical power systems use one of four different types of motion: - ANSWER linear motion
rotary motion
reciprocating motion
intermittent motion
oscillating motion
irregular motion
linear motion - ANSWER movement in a straight line
rotary motion - ANSWER any motion that moves in a circle (often connected to intermittent motion)
reciprocating motion - ANSWER linear back and forth motion
intermittent motion - ANSWER when movement starts and stops regularly
oscillating motion - ANSWER rotary back and forth motion that uses a single pivot point
irregular motion - ANSWER when the movement does not follow a constant pattern
friction - ANSWER a force that acts against motion when 2 surfaces rub together
in many situations....are used together in a system - ANSWER several types
