Question

An aircraft in level flight is travelling due east at a constant speed when it is acted on by a horizontal wind force of 800N.

Resolve the wind force into two perpendicular components and determine the component of the wind force along the line in which the aircraft is moving.

Answer 1

that will be fcos@
and cos30° = √3/2
800*√3/2 = f
692.8 N

Answer 2

The magnitude of the horizontal component of the force acting on the aircraft is 692.82 N.

Component of the force in the direction of the aircraft

The component of the force in the direction of the aircraft must be in horizontal direction.

The magnitude of the horizontal component of the force is calculated as follows;

Fx = Fcosθ

Fx = 800 x cos30

Fx = 692.82 N

Thus, the magnitude of the horizontal component of the force acting on the aircraft is 692.82 N.
