8 Demonstration Gyroscope 012-05327B Since d φ /dt = Ω , the precession speed, mgd = L Ω and the precession rate is given by Ω = mgd I ω where I is the rotational inertia of the disk and ω is the angular speed of the disk. To find the rotational inertia of the disk experimentally, a known torque is ...

9 012-05327B Demonstration Gyroscope So, once the linear acceleration of the mass (m) is determined, the torque and the angularacceleration can be obtained for the calculation of the rotational inertia. The acceleration isobtained by timing the fall of the hanging mass as it falls from rest a certai...

See Figure 1.3. ➁ Attach a Super Pulley with rod to the table using a table clamp. ➂ Wind a thread around the pulley on the center shaft and pas...

11 012-05327B Demonstration Gyroscope Alternate Computer Method: If a computer and Smart Pulley are used, the acceleration of the disk can be obtained byfinding the slope of the velocity vs. time graph. Measure the Radius ➀ Using calipers, measure the diameter of the pulley about which the thread is...

12 Demonstration Gyroscope 012-05327B Questions ➀ What happens to the direction of precession if the spin of the disk is reversed? ➁ How does the rate of precession change if the angular speed of the disk is increased? Acceleration Rotational Inertia Average Angular Speed of Disk Experimental Preces...
