For this part, you must user in F your vector formulation. That is, compute MA = B x F. Express your answer as a vector and convert "mm" to "m". a A b (b) Now use a different position vector, r, in the cross product. This time use rc to to compute the moment about point A. For this part, you must use rc in your vector formulation. Compute MA = rcx F. Express your answer as a vector and convert "mm" to "m". c) Do your answers agree? Yes or no. F By the way, how do you express the force as a vector when you are only given magnitude? Don't forget what we did on the last homework assignment: Position vector → Unit vector → Force vector.

Problem 5: Inputs: F = 81 i lb The force is applied at point A. (a) Use the cross product to compute the moment about point O. Mo = TOA X F. Express your answer as a vector. (b) Using the right-hand rule, interpret your vector result from the previous step and express this as a number with direction, CW or CCW. Use the absolute value here. (c) Use the scalar approach to compute the moment about point O. If you like, you can use the table we used for the previous problems, but a table is not required for this problem. (d) Do parts (b) and (c) jibe? Yes or no. (0, 3, 0) ft y A O F X Even though this is a 2D problem, notice that you must retain the z-term in your vector formulations. That's because the result of the cross product is a moment vector that is perpendicular to the plane containing r and F. In other words, if you're using the cross product, you are inherently constructing a 3D problem, even though the inputs look like a 2D problem.
