A large turntable with radius 6.00 m rotates about a fixedvertical axis, making one revolution in 8.00 s. The moment of inertia ofthe turntable about this axis is 1200 kg . m2. You stand, barefooted, atthe rim of the turntable and very slowly walk toward the center, along aradial line painted on the surface of the turntable. Your mass is 70.0 kg.Since the radius of the turntable is large, it is a good approximation totreat yourself as a point mass. Assume that you can maintain your balanceby adjusting the positions of your feet. You find that you can reacha point 3.00 m from the center of the turntable before your feet beginto slip. What is the coefficient of static friction between the bottoms ofyour feet and the surface of the turntable?

The moment of inertia for a set of objects of mass m; rotating about a common axis is defined as 1 = Σm₁r? 2 where r, is the distance of the ith object to the axis of rotation. If there are many particles that make up a larger object then this sum transforms into an integral, 4-fff or a. I = dV, V where p is the mass density and V the volume of the object. In this exercise we will explore moment of inertia by rolling two objects down an incline plane in the Experimental Math Lab Space.

A child's top is held in place upright on a frictionless surface. The axle has a radius of r 3.21 mm. Two strings are wrapped around the axle, and the top is set spinning by T T applying T = 2.40 N of constant tension to each string.
