Directions : The 3 - D problem figure shows the view of an object. Identify, its correct top view, from amongst the answer figures.
Show Hint
Look down on the object: the raised block at the back of the left bar, the slotted block on the right and the sloping step at the front must each appear as separate regions in the plan.
The object consists of a tall left bar that turns towards the front, a small raised block on the back end of that bar, a large block on the right whose right end has a slot (notch) cut into it, and a lower ledge at the front with a slanting edge. In the top view, the left bar appears as a vertical strip divided into two parts because the small raised block sits on its back end. The slanting front ledge appears as a trapezium at the bottom, and the large right block appears as a large rectangle whose slotted end shows as a separate rectangle in the top right corner, bounded by its own lines. Figure (1) has no slot rectangle at all, so it is wrong. Figures (3) and (4) show the slotted part as a thin strip or as a protruding narrower strip, which does not match the proportion of the slot. Figure (2) shows the slotted rectangle at the top right with the correct proportions, together with the strip, the divided left bar and the trapezium. Answer: (2) the second figure
