Question

Which of the two forces acting on the rigid rod causes clockwise moment?

Open in App

Solution

Moment is given by $\to τ = \to r \times \to F$
The force $F_{2} = 12 g f$ causes clockwise moment and force $F_{1} = 20 g f$ causes anticlockwise moment.

ii) is the rod in equilibrium?

Two forces $F_{1} = 5 N$ and $F_{2} = 8 N$ acting at points A and B on a rod pivoted at a point O, such that OA = $2 m$ and OB = $4 m$ . Calculate the total moment of the two forces about O.

State whether true or false.

At rotational equilibrium, the sum of clockwise moments equals the sum of anti-clockwise moments acting on a body.
