Determine the internal forces at point J for the structure shown, where member BD can only carry axial forces. Take the dimension a = 180 mm and the external load P = 350 N. * 225 mm 225 mm A PNV axial force: F₁ = shear force: SFJ= bending moment: BMJ = * 135 mm B a mm 120 mm * (tolerance 1 N, magnitude only) (tolerance 1 N, magnitude only) D (tolerance 100 N*mm, magnitude only)

Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall. Rope segment BC creates an angle of ¢ = 64.0 ° with the floor and rope segment CD creates an angle 0 with the horizontal. If both ropes BCA and CD can support a maximum tensile force Tmaz = 165 lb , what is the maximum weight Wmax of the crate that the system can support? What is the angle 0 required for D equilibrium? Express your answers numerically in pounds and degrees to three significant figures separated by a comma. • View Available Hint(s) vec ? Wmax, 0 = lb, degrees
