forces
force at A is pointed to the left and is in the center on the end
force at B is pointed to the right and is at the top and bottom of where C attaches. Can I send you a pic of the thing? It keeps telling me here that the attachment is bigger then 400X 400 and i made sure it wasn't
figure for post
I can't seem to get the figure to turn out right sorry about this, I will attempt to explain it in words.
the first rod AB is 0.9m long and has a diameter of d1=(30mm); 60kN<---- from the A end of this rod the second rod BC attaches to the B end of the first rod it is 1.2m...
Two solid cylinderical rods AB & BC are welded together at B & loaded as shown. Knowing that d(1)=30mm & d(2)=50mm, find the average normal stress in the midsection of (a)rod AB, (b) rod BC.
B____________C
125kN--->| |

My problem is to determine the magnitude and direction of the resultant force FR=F1+F2 and it's direction, measured counterclockwise from the positive x direction.
f1=250 lb @ 60 degrees from x
f2= 375 lb @ -45 degrees from x
Ok I got the magnitude by doing this:
(360-2(255))/2=-75...
