All Questions carry equal marks. ----1. Draw a parallelogram of sides 120mm and 90mm with included angle of 500. Construct an ellipse inside it. Draw a normal and tangent at any point on the curve. [16] 2. An inelastic string, 145 mm long has its one end attached to the circumference of a circular disc of 40 mm diameter. Draw the curve traced out by the other end of the string, when it is completely wound around the disc, keeping the string always tight. [16] A line, AB, 75mm long is in second quadrant with the end…show more content…
Draw the curve traced out by the other end of the string, when it is completely wound around the disc keeping the string always tight. [16] A cricket ball is thrown from the top of the building 7m high and at the highest point of flight, it just crosses a palm tree 14m high. Trace the path of the ball if the distance between the building and palm tree is 3.5m. In a parallelogram, the adjacent sides are 100mm and 70mm, and the included angle is 550, construct an ellipse. Find the major and minor axes and the foci. Draw a tangent at any point on the curve. [8+8] A line AB, 100mm long has its ends A 15mm above HP and 10mm in front of VP. The end B is in the third quadrant. The line is inclined at 450 to HP and 300 to VP. Draw its projections. [16] Draw the projection of a pentagonal plane ABCDE of side 25mm is resting on the HP on one of its edges (AB). The plane of the pentagon is inclined at 450 to HP and the top view of the edge is perpendicular to xy line. [16] A tetrahedron of 75mm long edges has one edge parallel to VP and inclined at 450 to HP and a face containing that edge is perpendicular to VP. Draw its projections. [16] A pentagonal pyramid of 20mm side of base and 50mm high, resting on its base on HP, having one of its base edges parallel to VP. Draw the top view, front view and side view. [16] A frustum of a cone 25mm top diameter, 50mm bottom diameter and 60mm high is placed in a cylindrical block of 75mm diameter and 50mm height such that, both the solids have the common axis. Draw the isometric projection of the combination of the solid. [16]
