🔍 Key Concepts

• Identify the thread form shown: a flat crest and root with angled sides at 29° is a key clue. • Compare common thread angles: 60° V-threads (standard bolts/NC stock), tapered pipe threads, and power screw threads used to transmit motion. • Think about which machine element most often uses a 29° power thread form for accurate linear motion.

💭 Think About

• Which of the options would most need a special thread form designed to transmit motion smoothly and resist wear, rather than just hold parts together? • Standard NC (National Coarse) bolts and heavy pipe both typically use a 60° V-thread. Which remaining choice is known for using a special, flatter-topped power thread? • Look at the 29° in the sketch: is that typical for everyday fastening threads, or for machine-motion screws?

✅ Before You Answer

• Verify which thread type has an included angle of 29° and a flat crest and root (this is a classic exam point). • Eliminate any choice that would normally use a 60° V-thread (standard fasteners and many pipe threads). • Ask: which component commonly uses an Acme/power screw thread form to convert rotary motion to linear motion?
