It help me a lot when to use cos and sin of the angle.
I appreciate

Can anyone explain how you choose your positive and negative rotations? Thanks!

[dontworry]

i see it as f trying to turn it counterclockwise. how is it clockwise?

Two men exert forces of F=400N and P=250N on the ropes. 1. Replace the two forces by an equivalent resultant force, Fʀ. same picture diffe
rent question need help.

Can we get pdf of there question becauce some time internet is not available.

I'm stuck, I don't understand the rotation part on the two forces. Help?

Why did you do Pcos45 and F(4/5)? Shouldn't they be sin?
