Two blocks are placed at the ends of a horizontal massless board, as in the drawing. The board is kept from rotating and rests on a support that serves as an axis of rotation. The block on the right has a mass of 5.8 kg. Determine the magnitude of the angular acceleration when the system is allowed to rotate.

The answer is ""

Explanation:

Let

While it is in balance, its net force mostly on a machine is zero where the board will rotate an upward torques were given by:

let,

where

angular acceleration

I = moment of inertia of the system

 Calculating the angular acceleration:

to be honest as much as i would love to answer this. i feel as if something's missing. just saying.
