# Multiple choice question for engineering

## Set 1

1. The surfaces of which intersect one another in lines which are called line of intersection.
a) True
b) False

Answer: a [Reason:] In engineering practice, objects constructed may have constituent parts, the surfaces of which intersect one another in line which are called line of intersection. A dome fitted on a boiler is one such example. The surface of the dome extends up to the line of intersection only.

2. The plane surfaces intersect in a ____________,the line of intersection between two curved surfaces is _________ and between a plane surface and curved surfaces is a _________
a) straight line, curve, curve
b) straight line, straight line, curve
c) straight line, curve, straight line
d) curve, curve, curve

Answer: a [Reason:] The plane surfaces (faces of prisms and pyramids) intersect in a straight line. The line of intersection between two curved surfaces (of cylinders and cones) or between a plane surface and curved surfaces is a curve.

3. Drawing straight lines on both the surfaces of solids and then pointing the points where they intersect and drawing lines which forms the line of intersection this process of finding the line of intersection is termed as _______ method.
a) assumption
b) line
c) removing material
d) cutting- plane

Answer: b [Reason:] A number of lines are drawn on the lateral surface of one of the solids and in the region of the line of intersection. Points of intersection of these lines with the surface of the other solid are then located. These points will obviously lie on the required line of intersection.

4. Selecting of particular plane in a series of planes drawn cutting the solid either parallel, perpendicular or oblique which cut the surface of one of the solids in straight lines and that of the other in straight lines or circles. This is called ________method.
a) assumption
b) line
c) removing material
d) cutting- plane

Answer: d [Reason:] The two solids are assumed to be cut by a series of cutting planes. The cutting planes may be vertical, edgewise or oblique. The cutting planes are so selected as to cut the surface of one of the solids in straight lines and that of the other in straight lines or circle.

5. When a solid completely penetrates another solid, there will be two lines of intersection. These lines are called_____________
a) line of interpenetration
b) concyclic curves of lines
c) hidden lines
d) inside line

Answer: a [Reason:] When a solid completely penetrates another solid, there will be two lines of intersection. These lines are called lines of interpenetration. The portion of the penetrating solid which lies hidden within the other solid is shown by dotted lines.

6. The line of intersection formed is straight line while two solids are intersecting the solids may be ________

## Set 2

1. The angle between the isometric axes is __________
a) 180 degrees
b) 60 degrees
c) 90 degrees
d) 120 degrees

Answer: d [Reason:] Isometric projection is a type of projection in which the three dimensions of a solid are not only shown in one view, but also their actual sizes can be measured directly from it. So it is needed that there exist equal angle between the axes for easy measurement so 360/3=120 degrees is chosen.

2. The value of the ratio of isometric length to true length is ________
a) 0.141
b) 0.372
c) 0.815
d) 0.642

Answer: c [Reason:] If we represent a cube in isometric view the diagonal of upper face of cube is equal to the true length of the diagonal. From it by drawing actual square around it and then calculating it gives (1/cos 30)/ (1/cos 45) =isometric /true =0.815.

a) 24.53 cm
b) 15.46 cm
c) 19.31 cm
d) 23.09 cm

Answer: a [Reason:] The ratio of isometric length to true length is 0.815 so here it is given isometric length of 20 cm. 0.815 = 20 cm / true length => true length = 20 cm /0.815 = 24.53 cm. Every time the true length is more than isometric length.

4. The true length of edge of cube is 15 cm what will be the isometric length?
a) 17.78 cm
b) 14.48 cm
c) 12.99 cm
d) 12.22 cm

Answer: d [Reason:] The ratio of isometric length to true length is 0.815 so here it is given true length of 15 cm. 0.815 = isometric length / 15 cm => isometric length = 15 cm x 0.815 = 12.22 cm. Every time the true length is more than isometric length.

5. The lines parallel to isometric axes are called ________ lines.
a) parallel
b) auxiliary
c) isometric
d) oblique

Answer: c [Reason:] The angle between the isometric axes is 120 degrees if any line is parallel to it then those are called isometric lines. Auxiliary lines may make any angle with horizontal and oblique is not related here.

6. The planes parallel to any of the two isometric lines are called ________ planes.
a) parallel
b) auxiliary
c) isometric
d) oblique

Answer: c [Reason:] The planes on which the faces of cube lie if it is placed in isometric view can be consider as the isometric planes which are parallel to two axes of isometric view which are x, y, z axes of isometric view.

7. Isometric view of cube is drawn the angle between the edge of cube and horizontal will be______
a) 15 degrees
b) 120 degrees
c) 45 degrees
d) 30 degrees

Answer: d [Reason:] Isometric view of cube is drawn the angle between the edge of cube and horizontal will be 30 degrees because as the angle between the base and axis lower to will be 90 degrees the angle between the axes is 120 degrees. 120-90 = 60 degrees.

8. Isometric view of cube is drawn the angle between the edge of cube and vertical will be______
a) 15 degrees
b) 120 degrees
c) 60 degrees
d) 30 degrees

Answer: c [Reason:] Isometric view of cube is drawn the angle between the edge of cube and vertical will be 60 degrees because the angle between the edge and horizontal is 30 and so angle between vertical and horizontal is 90. 90 – 30 = 60 degrees.

9. The true length of line is 40 cm and isometric view of it is drawn the length would decrease to ______
a) 28.28 cm
b) 32.6 cm
c) 34.6 c
d) 38.63 cm

Answer: b [Reason:] The ratio of isometric length to true length is 0.815 so here it is given true length of 40 cm. 0.815 = isometric length / 40 cm => isometric length = 40 cm x 0.815 = 32.6 cm. Every time the true length is more than isometric length.

10. The true length of the line is 30 cm and isometric view is drawn. How much length is reduced?
a) 24.45 cm
b) 25.98 cm
c) 4.01 cm
d) 5.55 cm

Answer: d [Reason:] The ratio of isometric length to true length is 0.815 so here it is given true length of 30 cm. 0.815 = isometric length / 30 cm => isometric length = 30 cm x 0.815 = 24.45 cm. 30 cm – 24.45 cm =5.55 cm.

11. The objects we see in nature will be in Isometric view.
