Mechanical Engineering : Engineering Mechanics - Quiz(MCQ)
In the journal bearings calculations, the moment is the cross product of which of the following two vectors?
A)
Force and Radius vectors
B)
Force and Radius scalars
C)
Radius and Force vectors
D)
Radius and Force scalars

Correct Answer : Option (C) :   Radius and Force vectors


Explanation : The cross-product must be created in the correct order. If no action is taken, the result is the polar opposite of the genuine result. As a result, the answer is the Radius and Force vectors, not the Force and Radius vectors. Because the moment, like many of the cross products, has a sense of direction, vigilance is required.
