250+ TOP MCQs on Curves Used in Engineering Practice and Answers

Civil Engineering Drawing Multiple Choice Questions on “Curves Used in Engineering Practice”.

1. Parabolic curves is not used in ________
a) Arches
b) Bridges
c) Sound reflectors

3. When the point is within the circle, the curve is called an ________
a) Inferior trochoid
b) Superior trochoid
c) Inscribed trochoid
d) Superior trochiod

Answer: a

5. For eccentricity in ellipse (e) which relation is correct?
a) e < 1
b) e = 1
c) e > 1
d) e = ∞

Answer: a
Clarification: Eccentricity can be defined as a parameter associated with every conic section. It can be thought of a measure of how much the conic section deviates from being circular. When (e < 1 Ellipse), (e = 1 Parabola), (e > 1 Hyperbola), (e = ∞ straight line), (e = 0 Circle).

6. When a uniform and flexible chain hangs from two pegs, its weight is uniformly distributed along its length. The shape it takes is called a _________
a) Catenary
b) Parabola
c) Hyperbola
d) Ellipse

Answer: a

7. A curve defined by an equation x2/a2 + y2/b2 = 1 is known as ________
a) Ellipse
b) Directrix
c) Parabola
d) Hyperbola

Answer: a

8. The curve generated by a point on the circumference of a circle, rolling along another circle inside it, is called a ________
a) Epicycloid
b) Epitrochoid
c) Hypocycloid
d) Trochoid

Answer: c

9. The curve generated by a point fixed to a circle outside its circumference as it rolls along a straight line is called a _________
a) Inferior epitrochoid
b) Superior trochoid
c) Inferior trochoid
d) Superior epitrochoid

Answer: b

10. The curve generated by a point fixed to a circle outside its circumference s it rolls along a circle outside it, is called _______________
a) Inferior epitrochoid
b) Superior trochoid
c) Inferior trochoid
d) Superior Epitrochoid

Answer: d
Clarification: An epitrochoid is a roulette traced by a point attached to a circle of radius r rolling around the outside of a fixed circle of radius R, where the point is at a distance d from the center of the exterior circle.

11. Which of the following is not true regarding concentric and eccentric circles?
a) Concentric circles have a common centre point
b) Eccentric circles have no common centre point
c) Concentric circles have no common centre point
d) Two or more circles with a common centre point are called concentric

Answer: d

12. Which of the following is not present in a circle?
a) Angle
b) Centre
c) Sector
d) Eccentricity

Answer: d
Clarification: Eccentricity can be defined as a parameter associated with every conic section. It can be thought of as a measure of how much the conic section deviates from being circular. Options like angle, centre and sector are there in a circle except the eccentricity.
