Question

I found the same question here but by lbs units. I tried to follow the processure but I always get my answers wrong, could you please help me

"As shown, a roller at point A and a pin at point B support a uniform beam that has a mass 26.0kg . The beam is subjected to the forces F1 = 57.0N and F2 = 95.0N . The dimensions are l1 = 0.600m and l2 = 2.10m . (Figure 2) What are the magnitudes FA and FB"

I found the same question here but by lbs units. I tried to follow the processure but I always get my answers wrong, could you please help me "As shown, a roller at point A and a pin at point B support a uniform beam that has a mass 26.0kg .

Explanation / Answer

Equate Ma=0

Fby=(F1*l1+F2cos(15)*l2)/(l1+l2)=83.03;

Fa*4/5=F1+F2cos15-Fbyso, Fa=65.73

Fbx=F2sin15-Fa*3/5=-14.85;

so, Fb=84.34
