Figure P2. Rope connection

Question

Consider the rope connection shown in  Figure P2 . Two ropes are attached to an eyelet.
      Each rope is in tension, with forces  F 1  and  F 2  acting along the ropes as shown.

For   θ = 31.1°  and  α = 19.1° ,  select which of the following is the correct
      expression for the magnitude of the resultant force  F R  due to  F 1  and  F 2 .
     
  Select the correct answer.

Figure P2. Rope connection

Answer

F_R = \sqrt{F_1^2 + F_2^2 + 2F_1F_2\cos(50)}

Answer

F_R = F_1 + F_2

Answer

F_R = \sqrt{F_1^2 + F_2^2 - 2F_1F_2\cos(130)}

Answer

F_R = \sqrt{F_1^2 + F_2^2 + 2F_1F_2\cos(130)}

Answer

F_R = \sqrt{F_1^2 + F_2^2}
