QUESTION:
The springs BA and BC each have a stiffness of 500 N/m and an unstretched length of 3 m. Determine the horizontal force F applied to the cord which is attached to the small ring B so that the displacement of AB from the wall is d = 1.5 m.
Step 1 of 2
Use the sum of the forces in the x direction to set up an equation relating the spring force to the applied force.Solve for the spring force using the given values,then solve for the applied force.
\(\sum F_{x}=0\)
\(\cos \theta=\frac{1.5}{\sqrt{(3)^{2}+(1.5)^{2}}}\)
\(\theta=63.4^{\circ}\)
