Question

Which of the following statements is false
about forces/couple?​

Answer 1

Q) Which of the following statement is false about forces/ couple?

a) Moment of the couple is a free vector.

b) Resultant and equilibrant are equal in magnitude and direction.

c) Resultant of a couple is always zero.

d) Parallelogram law is to be proved experimentally.

 

Option ( b) Resultant and equilibrant are equal in magnitude and direction is the false statement about forces/couple.

• When applying any physical action the strength or energy happening during that physical action is the force.
• When two equal such forces are applied but those are in the different directions then that is the term couple denotes.
• For a couple the moment is based on the two forces' distance, so it is a free vector.
• There are two forces acting in different directions, so the results will be zero in nature.
• Hence, option (b) is false here.
