Homework Statement
The mass of the homogeneous flat plate is 50 kg. Determine the reactions at the supports A and B. I've attached the diagram.
The Attempt at a Solution
I know I will need to find the center of mass. I don't remember exactly how to do it, but I found the centroid location first by using composite areas and the formula xbar=∑(x~)A/∑A and similar for y.
I found the centroid location to be at (0.566,0.183) m.
I have two questions.
If I find the center of mass, do I then just treat the mass as a concentrated load at that point horizontally and find the reactions using the moment about A or B and the sum of the forces in the y?
Can someone point me in the right direction for finding the center of mass from here?
Thank you!
