Q

Sawing faster than a rate of 40 to 50 strokes per minute while using a hand held hacksaw will generally __________.

🔍 Key Concepts

• Friction and heat created when metal rubs against metal • How tool speed vs. pressure affects wear on cutting edges • What happens to a hacksaw blade’s teeth when they are forced to work too fast

💭 Think About

• When you move the hacksaw much faster, what happens to the amount of heat at the cutting edge? • Does increasing stroke speed always mean more effective cutting, or can it start to damage or wear the cutting edge? • Think about how other cutting tools behave when pushed too fast—do they stay sharp longer or wear out more quickly?

✅ Before You Answer

• Consider how excessive heat affects metal cutting edges • Think about whether tooth wear increases or decreases with higher stroke speed • Ask yourself if the change is more likely to affect sharpness or cutting rate over time
