Homework Help Overview

The discussion revolves around calculating the torque for a square plate rotating around one of its edges, given its angular acceleration. The problem involves concepts from rotational dynamics.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the need for the mass of the plate to calculate its rotational inertia, which is essential for determining torque. There is a suggestion that the mass might be 80g, but this is not confirmed.

Discussion Status

The discussion is ongoing with participants exploring the necessary parameters for the torque calculation. Some guidance has been offered regarding the need for mass and rotational inertia, but no consensus has been reached on the values needed.

Contextual Notes

There is a mention of needing to post the complete problem and show work for further assistance, indicating a structured approach to homework help is encouraged.

CHECK OUT THIS PROBLEM

A SQUARE PLATE OF SIDE 5 cm IS ROTATING AROUND ONE OF ITS EDGES. IF THE ANGULAR ACCELARATION OF THE BODY IS 0.2 rad/s/s, FIND THE TORQUE.

ANSWER:2.0 * 10^(-5)
(TWO INTO 10 RAISED TO -5)

You need the MASS of the plate to calculate its rotational inertia I=1/2MR^2.
 
The mass should be given as 80g, right?
