#exercises_10b #Projections_of_straight_lines #Engineering_Drawing #engineeringgraphics 1. PROBLEM1: A line AB, 75 mm long, is inclined at 450 to the H.P. and 300 to the V.P. Its end B is in the H.P. and 40 mm in front of the V.P. Draw its projections and determine its traces. 2.PROBLEM2: Draw the projections of a line AB, 90 mm long, its mid-point M being 50 mm above the H.P. and 40 mm in front of the V.P. The end A is 20 mm above the H.P. and 10 mm in front of the V.P. Show the traces and the inclinations of the line with the H.P. and the V.P. 3.The front view of a 125 mm long line PQ measures 75 mm and its top view100 mm. Its end Q and the mid-point M are in the first quadrant, M being 20 mm from both the planes. Draw the projections of the line PQ. 4. A line AB, 75 mm long is in the second quadrant with the end A in the H.P. and the end B in the V.P. The line is inclined at 30° to the H.P. and at 45° to the V.P. Draw the projections of AB and determine its traces. 5. The end A of a line AB is in the H.P. and 25 mm behind the V.P. The end B is in the V.P. and 50 mm above the H.P. The distance between the end projectors is 75 mm. Draw the projections of AB and determine its true length, traces and inclinations with the two planes. 6. The top view of a 75 mm long line CD measures 50 mm. C is 50 mm in front of the V.P. and 15 mm below the H.P. D is 15 mm in front of the V.P. and is above the H.P. Draw the front view of CD and find its inclinations with the H.P. and the V.P. show also its traces. 7. A line PQ, 100 mm long, is inclined at 45° to the H.P. and at 30° to the V.P. Its end P is in the second quadrant and Q is in the fourth quadrant. A point R on PQ, 40 mm from P is in both the planes. Draw the projections of PQ. 8. A line AB, 65 mm long, has its end A in the H.P. and 15 mm in front of the V.P. The end B is in the third quadrant. The line is inclined at 30° to the H.P. and at 60° to the V.P. Draw its projections. 9. The front view of a line AB measures 65 mm and makes an angle of 45° with xy. A is in the H.P. and the V.T. of the line is 15 mm below the H.P. The line is inclined at 30° to the V.P. Draw the projections of AB and find its true length and inclination with the H.P. Also locate its H.T. problem no.3    • problem no. 3, Projections of lines 10(b) ...   projections of ponts    • PROJECTIONS OF POINTS   projections of straight lines-1    • PROJECTIONS OF STRAIGHT LINES - I   projections of straight lines-2    • PROJECTIONS OF STRAIGHT LINES - II   projections of planes    • PROJECTIONS OF PLANES   projections of solids-1    • Projections of solids-I   projections of solids-2    • Projections of solids-II   sections of solids    • Sections of Solids   orthographic projections    • Orthographic projections   isometric projections    • Isometric projections   Engineering drawing MSE-1    • Engineering Drawing MSE-I question papers ...   Engineering drawing MSE-2    • Engineering drawing MID-II question papers...   Engineering drawing ESE    • Engineering Drawing ESE Question papers wi...   Engineering drawing BITS    • Engineering Drawing (TOP-100 Bits) questio...   AUTOCAD    • AutoCAD   Computer aided analysis lab (FEM LAB)    • FEM/CAA LAB   MATLAB    • Matlab   Automobile Engineering    • Automobile Engineering   Finite element methods    • Finite element methods   CATIA    • CATIA   Computational methods in engineering    • Computational methods in Engineering   mechanical subject MCQ    • Dynamics of machinery  MCQ
