What is the rotational inertia of a solid iron disk of mass 41.0 kg with a thickness of 5.00 cm and radius of 30.0 cm, about an axis perpendicular to the disk and passing through its center?

Find out the moment of inertia of a semi circular disc of mass 10 kg and radius 3m about an axis passing through its centre of mass and perpendicular to the plane? (Take π2 = 10)

A uniform disk with mass 41.0 kgkg and radius 0.220 mm is pivoted at its center about a horizontal, frictionless axle that is stationary. The disk is initially at rest, and then a constant force 29.5 NN is applied tangent to the rim of the disk.Part AWhat is the magnitude v𝑣 of the tangential velocity of a point on the rim of the disk after the disk has turned through 0.190 revolution?Express your answer with the appropriate units.Activate to select the appropriates template from the following choices.

Consider a 20 kg uniform circular disk of radius 0.2 m. It is pin supported at its center and is at rest initially. The disk is acted upon by a constant force F = 20 N through a massless string wrapped around its periphery as shown in the figure. Suppose the disk makes n number of revolutions to attain an angular speed of 50 rad s–1. The value of n, to the nearest integer, is _______. [Given : In one complete revolution, the disk rotates by 6.28 rad]
