In the structure shown, force F is applied at point A at an angle of e in the direction shown. Pins at G, E, D, B, and C are all frictionless and all members are weightless. For the given values of F and e determine: F= 100 N 0 = 10 deg A G (a) The reactions at points G and E (b) The forces applied to member GDC at points C and D (c) The forces applied to member ABC at point B 70 m 50 m E D B Note: components of forces in x and y directions are enough. 15 m YA 60 m 20m

As shown, the truss is loaded by the forces P = 210 lb and P = 401 lb and has the dimension a = 3.30 ft L. P, Using the method of joints, determine FAR. FRG, and Frp, the magnitude of the force in each of the members connected to joint B. Assume for your calculations that each member is in tension, and include in your response the sign of each force that you obtain by applying this assumption. Express your answers numerically in pounds to three significant figures separated by commas. • View Available Hint(s) Hνα ΑΣφ vec FAB, FBC, FBD = lb
