Acceleration/gryo ratings for spinning wheel

AI Thread Summary
To measure the dynamics of a spinning wheel with a diameter of 800mm at speeds up to 100km/h, an accelerometer and gyroscope are necessary. The gyroscope should be rated for approximately 3900 degrees per second based on a calculated RPM of 650. The confusion lies in determining the appropriate acceleration ratings; acceleration in the radial direction relates to centripetal force, which measures velocity rather than acceleration. Angular acceleration is crucial for understanding motion along a circular path. Accurate specifications for both devices are essential for effective measurement and analysis.

I will need to put an accelerometer and or gyroscope on a spinning wheel. The wheel has a diameter of 800mm, with the device being 10-20cm from the centre of rotation. It will be need to cope with ground speed of up to 100km/h.

I am confused as to what ratings the device/s will need in terms of maximum gs for the accelerometer and dps for the gyroscope.

My current calculation of RPM comes out as around 650, which means I think the gryo would need to be rated at 650/60 * 360 degreees per second. Does that sound right? I'm more confused about the acceleration rating. Any pointers would be appreciated.

Acceleration in radial direction is given by the centripetal/centrifugal force - if you measure this you measure the velocity of the wheel, not its acceleration.
Acceleration in "angular direction" (along a circle) depends on the angular accelerations involved.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
