Accelerometer on a rotating wheel- Net force calculation

Click For Summary
The discussion revolves around the placement of two MEMS accelerometers on a car wheel, specifically the ADXL337 and ADXL377, which can measure accelerations of +/- 3g and +/- 200g, respectively. The car's maximum speed is 140 KMPH, and the wheel has a radius of 30 cm, where the net force at the center is zero. Participants emphasize the importance of considering centrifugal force during rotational motion when determining the optimal sensor placement along the wheel's radius. The original poster expresses difficulty in solving the problem and lacks equations to approach it. Understanding centripetal acceleration is crucial for addressing the placement challenge effectively.

Homework Statement



I have two analog MEMS accelerometers ADXL337, ADXL377. The ADXL337 can measure acceleration upto +/- 3g (where g = gravitational acceleration) and ADXL377 can measure upto acceleration of +/- 200g. More than this much amount of acceleration, would create noise and random datas. I have to put them on the wheels of a car. The maximum speed at which the car can move 140 KMPH. Thewheel of radius 30 cm. At the centre of the wheel net force is zero. if we have to put both the sensors along its radius, what is the maximum position for placing both the sensors along its radius?

The centrifugal force during rotational motion has to be considered.

Homework Equations

The Attempt at a Solution


I couldn't figure out a method for solving this problem.

No equations at all? Presumably you have studied centripetal acceleration?
