Question

Two forces of magnitudes 25N each acts vertically upward and downward on two ends of
rod having length 1 m freely pivoted at its mid point. Determine the resultant moment of force about the midpoint of rod.

Please answer with the formula.​​

Answer 1

Answer:

We know

$f = ma$

Let The Upper force be N¹ and Downward N².

Now N¹=M¹A¹

N²=M²A²

Substituting values Of N¹ and N²=25N.

So A¹M¹=A²M²=25

A¹M¹-A²M²=0
