A heavy solid cylinder with a mass of 600 kg and a radius of 0.50 m is securely fixed to a frictionless axle at its center. It has a long ideal rope tightly wound around it and hanging down from the cylinder about 1.0 m. Sally, who has a mass of 60 kg attaches herself to the rope and steps off a ledge, spinning the cylinder about the axle. If it takes 4.0 seconds for her to reach the ground...

A solid disk with mass M (1.00 kg)
and radius R (0.200 m) is sitting on a frictionless surface. We
analyzed the situation at left below, where a force F (2.00 N) is
applied for four seconds, by a string that has been wrapped around
the outer surface of a cylindrical disk.
Two students are debating the
following question. ‘The same force is applied for the same amount
of time, but this time by a string attached to the edge...

Rotational Inertia for Point Masses (theoretical valuel Part II: Rotational Inertia of Both Point Masses - Experimental Use equations (2) through (5) to derive an equation for I, the rotational inertia, in terms of m, 1,8, and a. Where m now represents the mass of the hanging mass. Box 2 center of rotation, the total rotational inertia will be MR2 where Mota = M, + M2, the total mass of both point masses. To find the rotational inertia experimentally, a...

4. An electric motor rotates at 1000 rpm and drives a pump through a soft start disc clutch. The pump has rotating mass of 250 kg and radius of gyration 0.5 m. The clutch has 5 friction surfaces having inner and outer radii of 250 mm and 350 mm respectively. The friction coefficient of the clutch material is 0.1. (a) For the first 5 seconds of operation, an axial force of 1 kN is applied through the clutch. Calculate the...

You are given that the “heart
shaped object” in Fig. 4 has a moment of inertia I = 0.5kgm2. Use
this to calculate
the change in angular momentum L of the object in 4s. Hint: L⃗ =
⃗τ∆t.
(b) This question deals with angular momentum conservation. Two
boys of mass 100 kg each stand at the center of a rotating
merry-go-round (MGR) in the shape of a disk of radius 1 m and mass
10 kg. The platform rotates at...
