Maharashtra HSC Engineering Drawing (Technical Science) case studies
Maharashtra HSC Engineering Drawing (Technical Science) · Put your knowledge to work in context.
Engineering Drawing is one of the technical-science subjects in the Maharashtra State Board HSC vocational/technical stream, taken by students who intend to move into diploma or degree programmes in mechanical, civil, production or architectural fields, or straight into drafting and workshop roles. The paper is a pencil-and-instrument examination: you are assessed on the accuracy of constructions, the correctness of projection conventions and the neatness of finished sheets, not on recall alone. The Maharashtra HSC Engineering Drawing (Technical Science) case studies are 5 cases and about 3,190 words.
1A2 Sheet Layout for a Cast-Iron Bracket
A candidate is laying out a drawing of a cast-iron bracket on an A2 sheet. The bracket’s overall size is 420 mm long, 260 mm high and 180 mm deep.
