Question

50 coplainer forces each equal to 100 newton are acting on a body each force make angle 7 degree with the preciding force fiind the resultant force

Answer 1

Given:

Coplainer forces are n= 50

Force acting on the body is F= 50 N

Angle is 7 degree.

To find:

The resultant force of all the coplainer forces.

Solution:

The net force be

F$_{net}$= n·F· cosФ

= 50·100· cos 7°

=500·(0.9925)

=496.273

So the resultant or net force F$_{net}$=496.273 N
