The problem figure shows the top view of an object. Identify the correct elevation amongst the answer figures looking in the direction of arrow.
Show Hint
The top view is a six-pointed star with a raised centre; list which edges from the apex are visible from the front.

The Correct Option is D
Solution and Explanation
Step 1: The star has twelve outline points, six tips and six inner points. All lines run from the centre to these points, so the solid is a six-pointed star pyramid whose apex is at the centre. The options show the double form (apex above and below the plan plane).
Step 2: In the front view the apex lies at the centre and the star outline lies on the middle horizontal line.
Step 3: Edges from the apex to the front inner points (at one third of the half width on each side) and to the front tip (centre line) are visible, and the edges to the outermost points form the outline.
Step 4: The edge from the apex to the points at the middle of each side lies behind a nearer face, so it is hidden.
Step 5: This gives the outer diamond, a centre line, two lines from each apex to points at about one third of the half width, and the middle horizontal line. That is option (4); options (1), (2) and (3) show extra lines to the mid-side points.

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
