How 3 kN-m?

In this equation if you people said me the using formula only send me using formula of this equation.

Send me formula dear.

What is the formula?

Sayad nasim said:   10 years ago
Hello dear one, formula is:

T(equivalent) = sqrt root (T^2+M^2).

=> 5^2 = sqrt root (4^2+M^2).

=> M = 3.

Sayad nasim said:   10 years ago
T (equivalent) = sqrt root (M^2+T^2).

Tulu said:   9 years ago
We know that

T = √ T^2 + √ M^2.

From this formula, we found that M = 3Knm.
