Consider the case above, but imagine that we remove the force and instead we add a cubic-shape body with one face in contact with the top surface of the half-body (that where the force was applied before). Consider the case in which we add gravity for all bodies (negative Y direction) and an additional horizontal force to the cube, attempting to make it slide along the top surface of the half-body. A qualitative sketch of the situation is provided below. Which of the following pairs of contact options are in principle equivalent, if applied between the cube and the top surface of the half body in this situation? (this part is worth 0.5 points) Note that you do not need to actually implement this in ANSYS, just answer the question based on the theoretical nature of the contacts. You can select more than one option, but all and only correct options must be selected to get any points for this subquestion.
