withthe construction are apt to take wrong centres for thetwo arcs. Limits to the data.—The angle a cannot be greater than 6, but mayhave any value from O to 6. When a = o, the line is horizontal, andtherefore parallel to the horizontal trace of the plane. When a = 0,that is, when the line and… … 191192 192. Problem.—Determine the plan and elevation of aline inclined at 6 to the vertical plane, and lying in aplane inclined at e to the horizontal plane. Find a, theinclination of the line to the ground. Let vth be the traces of the plane inclined at 0. First draw bAQ making an angle j3 with…
