1. A rigid object with moment of inertia 0.4 kg mº is spinning with angular speed of 0.2 rad/s around a fixed axis. A constant torque of 0.6 Nm is applied that increases the rotation speed of the object (no other force is present). (i) Calculate the angular acceleration of the object. (ii) Calculate the angular speed of the object at t = 4 s. (iii) Calculate the angle spanned by the object from 0 s to 4 s.

TASK-2 (20 MARKS) The mass moment of inertia with respect to an axis is defined as the product of the mass times the square of the distance from the axis. It is a measure of the resistance of the body to angular acceleration about a given axis. It determines the torque required to rotate the body about an axis with unit angular acceleration. Hence it plays an important role in the kinetics of a body during rotation about an axis....

2) Moment of Inertia for Multiple Objects We have loosely defined the moment of inertia as the difficulty or resistance encountered when trying to change an object's rotational motion. What if we were trying to rotation a combination of objects? a. Suppose you have a very light cloth pouch, and you place an apple of mass M=200 grams in it. You tighten up the satchel and start to swing it around, with the string in the satchel making a length...

Lab 8 Assignment: Moment of Inertia 1) Moment of Inertia for Different Systems The resistance to rotational motion change is more involved than for linear motion because it not only depends on what the mass is, but also on how that mass is distributed about the axis of rotation. The farther away from the axis the mass is distributed, the greater the moment of inertia. Using this simple definition, for each of the following pairs of objects, determine which of...
