题目内容
One of the electronic instruments used by Dr. Tichauer, 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 attached the attention of efficiency experts and time-and-motion-study engineers, but its value goes far beyond that. Dr. Tiehauer'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 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.
What are involved in the design of a new tool according to the passage？

W: Hello. My name's Jill Bush. I'm planning to go to a conference in Sydney for three weeks.
M: I see, Do you want the excursion fare or the full return fare？
W: Now, can I get a stopover on an excursion fare？
M: Yes, you are allowed only one stopover on the excursion fare.
W: Oh, I see, only one.
M: Yes. But of course, if you pay the full return fare then you can have unlimited stopovers. There's Singapore, Kuwait, Athens, you've really got quite a lot of choices you know.
W: Oh, It sounds good. You see, I've got a two-week holiday after the conference. How much is the full fare？
M: The full fare？ Well, that's really quite a lot. It's ￡1,204.
W: Yes. Well, it's once in a lifetime, you know. The thing is actually that I'm absolutely afraid of flying. I've never done it before.
M: Oh dear. Um...
W: And I'm hoping that I can persuade my two friends to go along with me.
M: Yes, that would be a good idea.
W: By the way, one of them is in Cairo at the moment. Would it be possible for me to stopover there on my way to Sydney？
M: Yes, of course. There are lots of flights to Cairo and, then plenty more onwards from Cairo to Sydemy.And then you can stay for as long as you like.
W: Oh, that's great! Thanks very much.
