The term shaft usually refers to a relatively long member of round cross section that rotates and transmits power. One or more members such as gears,

sprockets, pulleys, and cams are usually (16) to the shaft by means of pins, keys, splines, snap rings, and other devices. These latter members are among the “associated parts” considered in this text, as are couplings and universal

joint, which serve to (17) the shaft to the source of power or load.

Sometimes members like gears and cams are made (28) with shaft,

but more often such members (which also include pulleys,

sprockets, etc)are made separately and then(29) shaft. The

portion of the mounted member in contact with the shaft is the

hub. Attachment of the hub to the shaft is made in variety of

ways. A gear can be gripped (30) between a shoulder on the shaft

and a spacer, with torque being transmitted through a key. The

grooves in the shaft and hub into which the key fits are called

keyways.

read as follows.

Engineering design is the process of devising a system, component, or process to meet desired needs. It is decision making process(often iterative),in which the basic sciences, mathematics, and engineering sciences are applied to convert resources

optimally to meet a sated objectives and criteria, synthesis, analysis,

construction ,testing, and evaluation. The engineering design component of a curriculum must include most of the following features : development of student creativity, use of open-ended problem statement and use of modern design theory and methodology, formulation of design problem statement and specification, consideration of alternative solutions, feasibility considerations, production process, concurrent engineering design, and detailed system descriptions. Further, it is essential to include a variety of realistic constraints such as economic factors, safety, reliability, aesthetics, ethics, and

social impact.

31、what’s the main meaning of message (1)?

A) Engineering design is a systematic process B) materials engineer’s main

work

C) mechanical engineer’s has good idea D) electrical engineer’ main

duty

32、In the author’s opinion, the design process is very complex and should taken

into account many factors, from the message who should NOT join into the design team _______.

A) environmentalists,
