The last answer is wrong,it’s suppose to be y=22,014mm not “y=20,014” by the centroids

Centroid calculation is incorrect. You must define which axis you are taking area moment from. Then use parallel axis theorem to add local moments and global moment for each shape. Then divide by the calculated total area.

Do we not consider the UDL when calculating the bending moments?

Yes it's part of it

When taking moments about 'c', isn't the force 165KN and 45KN moving in a clockwise direction?

Will check it

It's anticlockwise

No it's clockwise

Do i have to convert mm to m or it doesn't matter?

It doesn't affect anything

How do you determine clockwise and anticlockwise direction?
