Practice 1 J. Byrne 2014

Below is a drawing representing a wine glass The curve ABC is part of an ellipse with a major axis 130mm & F is the focal point. The curve JKL is based on a parabola with K as the vertex 2 J. Byrne 2014

This drawing is the elevation of a lamp. The curve ABCD is based on an ellipse with a major axis 150mm & minor axis of 80mm. E & F are the foci points. The line AT is a tangent to the ellipse at A The curve GAH is based on a parabola with A as the vertex Draw the design showing all construction lines. 3 J. Byrne 2014

Draw this design full size and dimension correctly. All construction lines and POC’s must be shown. Please note the following: The curve AED is part of an ellipse with F & F1 its focal points. The curve ABC is a parabola with the vertex at B. The line CD is a tangent to the ellipse. The 5 windows are identical and equally spaced. 4 J. Byrne 2014 Template for a wooden toy aeroplane.
