Question

It two forces of magnitude 10kN and 20kN act
on a body, then their maximum resultant is​

Answer 1

Answer:

30kN

Step-by-step explanation:

when both force will act in same direction , thier impact will be maximum.

Answer 2

Answer:

The maximum possible resultant force from the two acting forces will be 30kN.

Step-by-step explanation:

We know that Force is a vector quantity and all vector quantities are direction dependent.

The resultant vector obtained from addition of two vectors aligned at a angle of $\theta$ is given by the expression:

$|\overline R|=\sqrt{A^2+B^2+2ABcos\theta}$

For maximum resultant, $\theta=0^{\circ}$ and $|\overline R|=A+B$,

So, the maximum resultant force will be when both given forces act in the same direction and its magnitude will be:

$F=10+20$  kN

$F=30$ kN

Thus, the maximum resultant force will be equal to 30kN.
