Question

A 8 3/4-inchcircular power saw rotates at 4400revolutions per minute. (Round your answers to two decimal places.) (a) Find the angular speed of the saw blade inradians per minute.
1 radians/min

(b) Find the linear speed (in feet per minute) of one of the 24cutting teeth as they contact the wood being cut.
2 feet/min (a) Find the angular speed of the saw blade inradians per minute.
1 radians/min

(b) Find the linear speed (in feet per minute) of one of the 24cutting teeth as they contact the wood being cut.
2 feet/min

Explanation / Answer

A) (4400 rev/min)(2 radians/rev)=8800=27646.02 B) v = r v =(8800 radians/min)(8.75 inches)(ft./12 inches)=20158.55
