the twodrawings, as shown in Fig.30 c, the arc Vz and theline fe^x* will intersect.Since the required H pro-jection of the swinging endof the line must be on boththe line and the arc, it mustlie at the point of intersec-tion, 6*. Likewise the Vprojection is found to fallat 6°. Note that if the - -… … EXERCISE SHEET X Take P at the right border line. No P projections are required., 1. The point a (72, 6, 4) is given. The line ab is 10 units long andslopes upward and forward from a, making an angle of 30° with H andan angle of 45° with V. Find its projections. (Two solutions.) 2. The point c (48,…
