Problem-1 Projection of Points – Draw the projection of points, the position of as per data given below: (1)A point ‘P’ 25 mm above H.P. and 20 mm behind V.P. (2)A point ‘Q’ 20 mm below H.P. and 25 mm behind V.P. (3)A point ‘R’ 25 mm below H.P. and 20 mm in front of…
Projection of Points – Point’s position will be given in data. We need to find out its projection on H.P. (Horizontal Plane) and on V.P. (Vertical Plane). There are maximum four quadrant wise positions possible of point. As we all know about quadrant, there are 4 quadrants exist. See figure below. Here are four quadrant…
Problem-1 Projection of Straight Lines – A line AB, 60 mm long, is inclined at an angle of 450 to HP. and 300 to VP. One of its end point A is in HP as well as VP. Determine its apparent inclinations. Procedure: Step-1 Draw a horizontal line, which is x-y line of some suitable…
Problem – 1 Projection of Solids – A pentagonal pyramid has height 60 mm and the side of a base 30 mm. The pyramid rests on one of its sides of the base on the H.P. such that the triangular face containing that side is perpendicular to the H.P. and makes an angle of 45…
Problem – 1 Section of Solids – A cone with base circle diameter 60 mm and axis length 75 mm is kept on its base on the ground. It is cut by a sectional plane perpendicular to H.P. and inclined at 600 to V.P. at a distance of 8 mm away from the top view…
Problem – (1) Development of Surfaces of Solids – A cone made up of Aluminium sheet with base circle diameter 65 mm and axis length 75 mm is kept on its base on the ground. A circular hole of 30 mm diameter is cut through the cone such that its axis remains perpendicular to V.P.;…
Problem -1, Engineering Curves – Draw Ellipse, Parabola and a Hyperbola on the same axis and same directrix. Take distance of focus from the directrix equal to 50 mm and eccentricity ratio for the ellipse, parabola and hyperbola as 2/3, 1 and 3/2 respectively. Plot at least 8 points. Take suitable point on each curve…
Point F Is 50 mm from a Directrix AB. A Point P is moving in a plane such that the ratio of its distances from F and line AB remains constant and equals to 2/3. Draw locus of point P {Take eccentricity equal to 2/3}. OR Draw an Ellipse by Directrix-Focus Method. Take distance of…
Definition of Engineering Curves – When a cone is cut by a cutting plane with different positions of the plane relative to the axis of cone, it gives various types of curves like Triangle, Circle, ellipse, parabola, and hyperbola. These curves are known as conic sections. * Vertical white line shows axis of cone in above…
Problem 2.1 Loci of Points – OBA is a simple crank chain. OB is a crank of 35 mm length. BA is connecting rod of 90 mm length. Slider A is sliding on a straight path passing through the point O. Draw the locus of the mid-point of the connecting rod AB for one complete…
