Question

A and B are two like parallel forces. A couple of moment H lies in the plane of A and B and is contained with them. The resultant of A and B after combining is displaced through a distance

• A. $\frac{2H}{A-B}$
• B. $\frac{H}{A+B}$
• C. $\frac{H}{2(A+B)}$
• D. $\frac{H}{(A-B)}$

Answer 1

The correct option is B $\frac{H}{A+B}$

Given

$A$ and $B$ are two like parallel forces.

A couple of moment $H$ liesin the Plane of $A$ and $B$ and is contained with them.

$(A+B)d=H$

So the resultant of $A$ and $B$after combining is displaced through a distance

Hence the correct answer is $d=$ $\frac{H}{(A+B)}$
