The truncated lower portion of a pyramid is called (a) Prism (b) Frustum (c) Cube (d) Cone (ENGG-GRAPHICS-CBSE-12-2018)1 AnswerA sphere (diameter 50 mm) is placed centrally on the top hexagonal face of a hexagonal prism (base edge 30 mm and height 40 mm). Two base edges of the prism are parallel to V.P. The common axis is perpendicular to H.P. Draw the isometric projection of the combination of solids. Show the common axis and indicate the direction of viewing. Give all dimensions. (ENGG-GRAPHICS-CBSE-12-2018)1 AnswerA vertical triangular pyramid (base edge 40 mm and axial height 60 mm) is resting on its base on H.P. One of its base edges is perpendicular to V.P. Draw its isometric projection. Show the axis and indicate the direction of viewing. Give all dimensions. (ENGG-GRAPHICS-CBSE-12-2018)1 AnswerThe slant height of the frustum of a cone is 5 cm. If the difference between the radii of its two circular ends is 4 cm, write the height of the frustum. CBSE Mathematics1 AnswerA bucket made up of a metal sheet is in the form of a frustum of a cone of height 16 cm with radii of its lower and upper ends as 8 cm and 20 cm respectively. Find the cost of the bucket if the cost of metal sheet used is Rs. 15 per 100 cm2. CBSE1 AnswerConstruct an isometric scale. (ENGG-GRAPHICS-CBSE-12-2018)1 AnswerA ray of monochromatic light is incident on one face of an equilateral prism at an angle equal to 3/4th of the angle of the prism(Physics CBSE 2018) 1 AnswerThe diameters of the lower and upper ends of a bucket in the form of a frustum of a cone are 10 cm and 30 cm respectively. If its height is 24 cm, find : (i) The area of the metal sheet used to make the bucket. (ii) Why we should avoid the bucket made by ordinary plastic ?0 AnswerWhich one of the following represents a closed crystallographic form? (-Gate Geology and Geophysics 2014)1 AnswerIn a single riveted lap joint, the plates to be joined are (a) In contact with each other at the ends (b) Overlapping each other (c) Inclined to each other (d) Kept at a distance of 10 mm from each other (ENGG-GRAPHICS-CBSE-12-2018)1 AnswerWhich of the following is not a part of an unprotected flange coupling ?
