Question
1. Determine FB. Express your answer using two significant figures.
2. Determine the magnitude of
F? A+F? B.Express your answer using two significant figures.
Two snowcats tow a housing unit to a new location at McMurdo Base, Antarctica, as shown in the figure(Figure 1) . The sum of the forces F? A and F? B exerted on the unit by the horizontal cables is parallel to the line L, and FA=4000N. 1. Determine FB. Express your answer using two significant figures. 2. Determine the magnitude of F? A+F? B. Express your answer using two significant figures.Explanation / Answer
A.
F(B)sin(30) = F(A)sin(50)
F(B) = 2(4000)sin(50) = 6128.35 N
B.
F(A) + F(B) = 4000*sin(100 deg)/sin(30 deg) = 7878.46 N
