Hey!

I have been trying to solve this problem without success. Any help will be appreciated

Resolve the 170 N force into three parts: one of which is parallel to OQ, another parallel to OP, and the third parallel to the y axis. (See the graph)

Are these the components of F in these directions?

Pay attention to the last question. the answer is "No". I have already found the components of the force in Fx, Fy and Fz directions. So the "parts" to be found are different from the components.

Trigonometric equations

What I used to find the Fx, Fy and Fz components:

[itex]Fz = F * sinγ[/itex]

[itex]Fy = F * cosγ * sinβ[/itex]

[itex]Fx = F * cosγ * cosβ[/itex]

I found the Fx, Fy and Fz components using the equations above: they are 80, 120 and 90, respectively.

I also calculated the uni vector of F and of OQ (see attachment). I have also calculated the sides of several right triangles.

Now my problem is that I don't have an idea how to connect all the dots and complete the solution.

Thank you in advance!
