Any point on thiselement will be a point on the surface of the cylinder. Theelement projected at xy has two plan views, one at… … Fig. 8o. Fig. 8i. by its plan view only, two V projections would be possible, oneat q and one at x, since the element through Q has two possibleV projections. In given problems it will always be stated onwhich element to take the point. 91. Proposition 22. Given the axis and right section of…
