Questions & Answers

Q: What are the three types of geared mechanisms discussed in the video?

The three types of geared mechanisms discussed in the video are rotate/rotate, rotate/translate, and translate/translate.

Q: What is the difference between spur gears and bevel gears in terms of axle positioning?

Spur gears have axles that are parallel to each other and rotate in a common plane, while bevel gears have axles at an angle and meet at a point.

Q: How does a rack and pinion mechanism work?

A rack and pinion mechanism consists of a gear (pinion) that rotates and a rack that translates instead of rotating. The pinion's movement causes the rack to slide.

Q: What is an example of a rotate/translate geared mechanism shown in the video?

An adjustable spanner is an example of a rotate/translate geared mechanism shown in the video. Depending on the frame of reference, either the handle or the jaw can be considered the frame, leading to a different type of motion.

Summary & Key Takeaways
