mm long. The slider C is sliding on a straight path passing through the point A. Draw the
locus of the mid point P on the connecting rod BC for one complete revolution of the crank
0B.
A thread unwound itself from a cylindrical drum of 60 mm in radius. Draw the locus of the 6
free end of the thread for unwinding through an angle of 180?.
0R
T wo cranks A0 and BQ Oscillates about 0 and Q respectively. Trace the locus of the mid 7
point P of the connecting Link AB, AO=45 cm, BQ = 67.5 cm, AB = 37.5 cm.
A circle of 40 mm diameter rolls along the inner circumference of another circle of 120 mm 6
diameter. Draw the path of point P on the circumference ofa rolling circle for one complete
revolution. Draw the normal and tangent at any point on a curve.
\
Distance between the end projectors of line AB 80 mm long is 60 mm. It's one em; A is 6
20 mm above HF. and 30 mm in front of V.P. Draw the projections of a line if it is parallel
to HP. and also measure inclination with V.P.
A thin composite plate, Consists of a square ABCD of 60 mm sides with an additional 7
semicircle constructed on CD as a diameter. The side AB is in the V.P. and makes 30? with
the 11.? and the surface of the plate makes an angle of 45? with the V.P. Draw its projections.
OR
A line AB of unknown length has its end A in HP. and 25 mm in front of V.P. End B is 25 6
mm in front of V.P. and 55 mm above H.P. Draw the projection of line If it is inclined at
30? to HP. and then ?nd the TL. of line AB.
A semi-circular thin plate of 60 mm diameter rests on the HP. on its diameter which is 7
inclined at 45? to the V.P. and the surface is inclined at 30? to the HP. Draw the projections
of the plate.
