Q1 Weight: 100.00 % In the figure below, each of springs AB, C'B, and D B have equivalent stiffness of K [b/in. The original length of spring DB is 2 ft. After the force F' is applied by the man, the spring D B has a stretched length of 3.2 ft. Write the equation of equilibrium in the x direction and calculate: COLLAPSE IMAGES F =6001b The stretch in spring D B (use in). m ENTER 3 tries remaining. 20 point(s) possible The stretched length of springs AB or C'B (use ft). ft ENTER 3 tries remaining. 20 point(s) possible The stiffness (K) of all three springs. Ib/in ENTER 3 tries remaining. 20 point(s) possible The force in spring DB. lb ENTER 3 tries remaining. 20 point(s) possible The force in springs AB or C'B. lb ENTER 3 tries remaining. 20 point(s) possible
