Design of all the new tools and implements is based on careful experiments with electronic instruments. First, a human "guinea pig" is tested using a regular tool. Measurements are taken of the amount of work done, and the buildup of heat in the body. Twisted joints and stretched muscles cannot perform as well, it has been found, as joints and muscles in their normal positions. The same person is then tested again, using a tool design according to the suggestions made by Dr. Tichauer. All these tests have shown the great improvement of the new designs over the old.
One of the electronic instruments used by Dr. Tichauer, the
myograph
, makes visible through electrical signals the work done by human muscle.
Another machine measures any dangerous features of tools, thus proving information upon which to base a new design. One conclusion of tests made with this machine is that a tripod stepladder is more stable and safer to use than one with four legs.
This work has attracted the attention of efficiency experts and time-and-motion-study engineer, but its value goes far beyond that. Dr. Tichauer’s first thought is for the health of the tool user. With the repeated use of the same tool all day long on production lines and in other jobs, even light manual work can put a heavy stress on one small area of the body. In time, such stress can cause a disabling disease. Furthermore, muscle fatigue is a serious safety hazard.
Efficiency is the by-product of comfort, Dr. Tichauer believes, and his new designs for traditional tools have proved his point.
From the passage we know that joints and muscles perform best when________.
选项
A、they are twisted and stretched
B、they are in their normal positions
C、they are tested with a human "guinea pig"
D、they are tested with electronic instruments
答案
B
解析
事实细节题。第一段第四句指出,扭曲的关节和伸展的肌肉不能像处于正常位置的关节和肌肉那样很好地发挥作用。由此可知,关节和肌肉处于正常位置时是它们表现最好的时候,故B项为答案。
