Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

1) A student measures the acceleration of a disk with 12 cm radius. She attaches a 150 g mass to the string and winds it around a 1 cm radius axle. When the mass drops, the tension from its weight creates an angular acceleration of 1.7 radians/s² on the disk. (This refers to sections 1.1 through 1.4 and utilizes the equations in the theory. Be careful to use the correct radius when you use equation 4.) a) Calculate the moment of inertia of the disk. b) Calculate the mass of the disk. 2) She adds the cylinder with inner and outer radii are 5 and 5.5 cm respectively. Using the same mass and axle radius as before she measures a new angular acceleration of 1.46 radians/s². a) Calculate the moment of inertia of the disk and cylinder together. b) Calculate the moment of inertia of the cylinder by itself. c) Calculate the mass of the cylinder.
