Joseph pulls up on the handle of a door at an angle of 55 degrees to the vertical. If he uses a force of 30 N, what is the force in the upward direction?

Respuesta :

Answer:

Fy = 17.21 N

Explanation:

In order to do this, we can actually go and do a drawn of this.

Picture 1, has the drawn and the angle.

According to that, the angle of 55° is to the vertical, so, the angle to the horizontal wpould be 35°.

To calculate the component of "y" we should use the following trigonometric expression:

cos55° = Fy/F

Solving for Fy:

Fy = F cos55°

Replacing we have:

Fy = 30 cos 55°

Fy = 17.21 N
