Consider a rectangular block with dimensions as shown in the first sketch and three force and couple systems at points A, B and D as in the second sketch. The two blocks in the sketches are to be interpreted as the same block and the sketches are overlapping. S R D A P 2m B с 3m 4m Q 20kN ← 60kNm 20kN 60kNm 20kN 40kNm 20kN 40kNm 60kNm Determine which force and couple system (s) at points A, B and D will be equivalent to the force and couple system at point Q. There may be more than one equivalent system. Incorrectly selected options will be marked negatively. The minimum mark for this question is 0. No force system. The force system at point A. The force system at point B. The force system at point D. m to the Submit part (b) If the force system at point B is reduced to an equivalent force system in its simplest form, where does the line of action of the force intersect the plane in the which rectangle APQB lies? Describe this by indicating (i) how far to the left or the right of the line segment AP and (ii) how far to the front or the back of the line segment PQ does this point lie. The point lies m to the of the line segment AP and of the line segment PQ. 3 marks Unanswered Submit part 4 marks Unanswered Consider a rectangular block with dimensions as shown in the first sketch and three force and couple systems at points A, B and D as in the second sketch.
