Mechanical Engineering Quiz

What is redundant support?

What is the Iron-Carbon phase diagram?

Which of the following methods is best for detecting interior flaws in the castings?

Which of the following is correct? (For A representing the vector representation of the

axis of rotation, r the radius vector and F the force vector)

If a force is applied at any point in its line of action and is still creating the same

moment about any fixed point, say P, then the force is said to be a sliding vector. What is

the name of this property?

If the supports are properly aligned, the reaction forces developed adequately support

the body

If A is any vector with Ai + Bj + Ck, then what is the y-axis component of the vector?

Which of the following forces do not cause the rotation. Suppose the rotation is

considered inside the body's axis or the centroid axis of the body.

For a vector F, Fcosβ is equal to zero. What does this refer to?

Which of the following is correct for the moment of couple M caused by two forces of

the same magnitude F and are separated by a distance of r?

Determine the vertical components of the reaction on the beam caused by the pin at Q.

The force 60N is multiplied by ten and then is applied. Which of the following axis system is being satisfied by tetragonal crystal system?

Which of the following types of light is preferred for using fluorescent penetrant in

liquid penetrant testing (LPT) method?

For two vectors defined by an arrow with a head and a tail. The length of each vector and

the angle between them represents:

Which of the following material has the carbon varying from 4.3 to 6.67%?

Which of the following axis system is being satisfied by tetragonal crystal system?

Which one of the following can act as a modifier in the glass-forming process?

Which one of the following is least symmetrical?

What if we multiply a scalar to the unit vector?

Which statement is right?

Iron possesses BCC crystal structure up to (in degree centigrade)?

What is the scale range of the Mohs hardness test?

Determine the value of the q, parallel to the z-axis. That is the point of intersection of the projections of the points A, B, and C parallel to the xy plane. The distance between the tri-section point and the points A, B, and C be equal to 0.6m. If two equal vector forces are mutually perpendicular, then the resultant force is acting at

which angle as compared to one of the vector?
