This one is really discouraging me. It looks sooooo easy since the forces are each in one direction
The way I have usually handled these as a procedure is: Find [itex]F_r[/itex] and then find [itex]M_r[/itex] about some point and then decompose [itex]M_r[/itex] into components that run parellel and perpendicular to [itex]F_r[/itex]. Then I can usually find P(x,y)
If I were to move everything to point A I would have:
[itex]F_r=500i+300j+800k[/itex]
And I would also have to find the couple Moments about A:
[itex]M_x_A=4(800)=3200[/itex]
[itex]M_y_A=0[/itex]
[itex]M_z_A=6(300)=1800[/itex]
I am just unsure where to go from here? Or is this all wrong altogether?
