Question 395024
Assuming that a table saw blade has a diameter of 12 inches and spins at 3450 revolutions per minute(RPMs), determine how fast the tip of the teeth of the saw blade are traveling in miles per hour.
------------
v = 12*pi*3450 in/min
v = 3450*pi ft/min
v = 3450*pi*60/5280 mi/hr
v = 3450*pi/88 mi/hr
v =~ 123 mph
