APPLIED SCIENCES 695 The scale of plan is of an inch to foot The plan itself is rectangle by To make the problem of any value the proportion of the scale to the actual measure- ment should be shown and stated Two indefinite lines meet in point and in plan appear to make the angle at one of 115 The actual angle is 90 Find the plane containing them The vertical trace of plane is inclined at 40 and the horizontal trace at 60 to xy What is the inclination of the plane 8a second plane has the inclination of its traces reversed and meets and intersects the first plane above mentioned Show the angle between the planes Two adjacent edges of cube 75 in length are inclined at 45 and 30 to the ground respectively Show plan and elevation of the cube 10 Three points appear in plan as an equilateral triangle of 2-5 edge but is 75 and above the paper Find the true length of each of the sides of the triangle and the inclination of the plane containing it 11 cone of convenient dimensions has cylinder passing through it The cone stands on its base axis vertical cylinder horizontal axis inclined at 40 to vertical plane 12 Show the shadow of the combined solids on one or both of the planes of projection as the case may be FIEST YEAR Construct scale to show full size Draw square of feet side to this scale Show all the angles you can construct with compasses alone from given point on one side of straight line Show the plan and elevation of this square when line joining one angle to the centre of the opposite side is inclined at 40 Show the plan and elevation of your instrument box without the tray when the lid is open to the extent of 30
