Problem 6.90

Since the brace shown must remain in position even when the magnitude of P is very small, a single safety spring is attached at D and E. The spring DE has a constant of 50 lb/in. and an unstretched length of 7 in. Knowing that l 5 10 in. and that the magnitude of P is 800 lb, determine the force Q required to release the brace.
