mechanical engineering. I follow your moments from the point A as this is what I have. Its the next part I don't know how to get from there to my answer of F1=6 and F2 =2. This is where I become unstuck...
Yeah I 100% have the same as you for 0.5F1-1.5F2-2Rb
How do I get from that though to the final answer of F1=6 and F2=2
Been at this for days and cant clear this final hurdle to finish this up.....
Currently Iam no further on than where I started....
You have two equations in two unknowns, F_1 and F_2:
Using a technique you learned in the 9th grade: rearrange the first equation so that F_2 is by itself:
and subsutite for the F_2 term in the second equation:
and rearrange to solve for F_1:
So that's F_1. Now use this value of F_1 back in the earlier equation for F_2:
