Topic 1. Test

E1: Hi, I’m Ian Moore. I’m here for an interview.

E2: It’s nice to meet you, Ian. Tell me about your work experience.

E1: Well, I worked for Escribano for twelve years.

E2: What were your job duties?

E1: I assessed old engine models. Then I made suggestions to improve them.

E2: Did you design any engines?

E1: Not on my own. I designed new parts for older models.

E2: If we hire you, you’ll design new ones as well.

1: Dani, could you do me a favor?

2: Sure, Ivan. What is it?

1: Could you please go to the hardware store? I need a couple of bearings.

2: Of course. What kind do you need?

1: I need two straight roller bearings.

2: Okay, didn’t you break a ball bearing earlier?

1: That’s right, I almost forgot. I also need an inner race for a ball bearing.

2: Got it. I’ll head out right now.

1: David, I noticed a problem with your designs. This coupling won’t work.

2: What’s wrong, Elsa?

1: The input and output shafts aren’t aligned.

2: You’re right. It looks like there’s a little bit of offset.

1: Yeah. It means we can’t use a rigid coupling. It’ll break.

2: Oh, you’re right. We’ll have to use a flexible coupling instead. What do you recommend?

1: I think a beam coupling would work best.

2: I agree. We’ll use that.

1: How are the plans for the new transmission system?

2: Pretty good. We need to decide what kind of gear to use.

1: We should use bevel gears. The shafts meet at right angles.

2: That makes sense. But I’d like to use helical gears if possible.

1: Good idea. It’ll reduce noise from the gear teeth.

2: Exactly. They’ll mesh more smoothly.

1: I’ll look for beveled helical gears.
