Question

The resultant for a number of forces acting at a point is given by

Answer 1

Answer:

Vector sum of the vectors

Answer 2

Answer:

Explanation:

Resultant for a number of force at point is given by summing the forces in x direction and force in Y axis

For example

$F_1\ force\ at\ \theta _1$

$F_2\ force\ at\ \theta _2$

$F_3\ force\ at\ \theta _3$

Forces in the x direction

$F_x=F_1\cos \theta _1+F_2\cos \theta _2+F_3\cos \theta _3$

$F_y=F_1\sin \theta _1+F_2\sin \theta _2+F_1\sin \theta _3$

$F_{net}\ is\ summation\ of\ F_x\ and\ F_y$

$F_{net}=\sqrt{F_x^2+F_y^2}$
