2. A 50 lbf force is applied to a corner plate as shown. a. Define a 3D position vector from the point A to the applied force in Cartesian form. b. Define a 3D vector for the applied force in Cartesian form. c. Use the cross product to find the effective moment about point A due to the applied load. d. What reaction load is carried if the plate is only supported at point A? Verify: that the moment direction found using the cross product seems reasonable. Also verify that the units for the answer in part B seem reasonable. 3 in. B 5 in. 10 in. 50 lb 30°
