The resultant force of a couple is ………?
A
Infinity
B
Zero
C
One
D
Half
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Note: moment of a couple = force × length (fL)
The tangential force is actingin an opposite direction alongside its length
i.e f1 L1 = f2L2
f2L2 − f1 L1 = 0(i.e Zero)
