Nov 15 2011nbsp018332a ferris wheel with a radius of 8 m makes 1 revolution every 10 seconds when he is at the top essentially a diameter above the ground a man releases a ball how far from the point on the ground directly under the release point does the ball land a 0 b 10 m c 80 m d 91 m
Jul 16 2014nbsp018332other than the tendency to run hotter due to surface speed issues the material doesnt know the difference between being cut twice a revolution by a two flute at 6000 rpm or 4 times by a four flute at 3000 rpm hence switching from a two flute to a four flute is like doubling your spindle speed
Sample problem you are on a ferris wheel that rotates 1 revolution every 8 seconds the ferris wheel operator brings the wheel to a stop and puts on a brake that produces a constant acceleration of 01 radianss 2 a if your seat on the ferris wheel is 4 m from the center what is your speed when the wheel is turning at the rate of 1 revolution every 8 seconds

Sep 26 2017nbsp018332as stated previously increasing the number of flutes on a tool limits the size that the flute valleys can be while adding a 5 th flute to a 4 flute tool theoretically gives you 25 more material removal per revolution with an appropriately increased feed rate feeding the tool that much faster may overload the tool the 25 increase in
Flutes are what we call the individual cutting edges or teeth that make up the spiral on an end mill the number of flutes the endmill has is crucial depending on the material you want to cut and the capabilities of your machine the most common options are 2 3 or 4 flutes unless you know exactly what youre doing you never want to
