Electrical saw with linear speed

Click For Summary
SUMMARY

The discussion centers on calculating the linear speed of a hand saw to match the cutting speed of a circular saw with a 23 cm diameter blade spinning at 3800 RPM. The correct approach involves using the formula v = wr, where w is the angular speed in radians per second. The participants emphasize the importance of converting RPM to rad/s to achieve accurate results. One user successfully solved the problem after clarifying the conversion process.

PREREQUISITES
  • Understanding of angular velocity and linear velocity relationships
  • Familiarity with the formula v = wr
  • Knowledge of unit conversion from RPM to rad/s
  • Basic grasp of circular motion concepts
NEXT STEPS
  • Learn about converting RPM to radians per second
  • Study the application of the formula v = wr in different contexts
  • Explore the physics of circular motion and its real-world applications
  • Investigate the design and mechanics of circular saws
USEFUL FOR

Students studying physics, engineers working with mechanical systems, and anyone interested in the mechanics of cutting tools.

1. A 23 cm diameter circular saw blade spins at 3800 rpm. How fast would you have to push a straight hand saw to have the teeth move through the wood at the same rate as the circular saw teeth?



Homework Equations


v=wr
τ=Iα
τ=rFsinθ

The Attempt at a Solution


tried to multiply the rmp by the radius of the circular saw, but didn't give me a correct answer

Could you show us your working.
(Did you remember to use rad/s for the angular speed?)
 
I already solved it thank you C:
