2.50 Las fuerzas P y Q se aplican al componente de una pieza de en- samble de avión como se muestra

Exercise 2.50 from the book VECTOR MECHANICS FOR ENGINEERS: STATICS. Ninth Edition 2.50 Forces P and Q are applied to an aircraft component as shown in the figure. Knowing that the component is in equilibrium and that the magnitudes of the forces exerted on bars A and B are FA = 750 lb and FB = 400 lb, determine the magnitudes of P and Q.
