A 230 - newton box rests on a plank 5 meters long?

A 230 - newton box rests on a plank 5 meters long. One end is 1. 2 meters higher than the other end. Find the components of the force the box exerts.

En resumen

The components of the force the box exerts are Wx = 223. 27 N and Wy = 55. 21 N. Being Wx the component over x axis and Wy the component over y axis. Angle A calculationCos A = 1. 2 / 5 = > A = ArcCos (1.

The components of the force the box exerts are Wx = 223.

27 N and Wy = 55.

21 N.

Being Wx the component over x axis and Wy the component over y axis.

Angle A calculationCos A = 1.

2 / 5 = > A = ArcCos (1.

2 / 5)A = 76, 11°Then we will calculate components of force W (weight).

Free - Body diagram is annexedWx = WSen76.

11° = 230Sen 76.

11°Wx = 223.

27 NWy = WCos76.

11° = 230Cos76.

11°Wy = 55.

21 N.
