question f please just don't get it really. If u don't mind could u write the solutions on paper and post it. It would be much appreciated

and we need to find f1 and f2
6. I'm presuming you need to find F1 and F2 given that the forces are in equilibrium? If so, it probably helps to resolve horizontally, and then vertically, to get two eaquations.

For example, if we say that upwards is positive and resolve vertically, we get:

vertical component of F1 + vertical component of F2 - 200 = 0

what are the equations of the components

I can't exactly post you a full solution but I will certainly push you in the right direction.

Firstly, I'm just going to assume the system is in equilibrium, if it's not, you should provide information about that.

So the key here is to construct a set of two equations which show equilibrium of forces horizontally and vertically.

If you draw a horizontal line through the point where the forces are coming from that would be helpful. Then you can split degrees into 90 degrees (between the 200N and the horizontal) and 50 degrees (between the horizontal and N).

Do the same for .

You can then split and into horizontal and vertical components. For the horizontal component would be and the vertical is .

Once you have split the forces into horizontal and vertical components, the sum of the vertical components for the two forces must be equal to 200. And the horizontal components of both forces are equal to one another.

Then you just have 2 equations with 2 unknowns which you can solve for.
