## Homework Statement

I am currently doing an internship and as part of my assignemnt I have to calculate the dynamic load on the bearing of a certain part that is rotating about a fixed point.

https://www.physicsforums.com/attachments/chute-png.103400/

This is the part that moves ( the brown part rotates about the back shaft)https://www.physicsforums.com/attachments/paint-chute-png.103401/ The Ww is 8 kg,

The Ws = 6 kg

the weight of the blue boxes (Wp) on it is total 50 kg and it is centerized

Tetha is 20-60 degrees

I would like to what the dynamic force load is

w = 0.5 rad/s

## Homework Equations

Sum of moments = Moment of inertia* angular acceleration

F= M*a

## The Attempt at a Solution

I assumed all the masses are combined to become 64 Kg acting at the center of the wood

but I got the force to be tiny.

I am lost on how to start [/B]
