Resolution of forces into x and y components.
A roof purlin, supported by a rafter, must support a 300# vertical snow load. Determine the components of P, perpendicular and parallel to the axis of the rafter.
Homework Answers
At purlin
Given that,
Vertical snow load applied on a roof purlin is 
From figure,
The component of the force 
which is parallel to the axis of rafter
Therefore, the component of the force 
which is parallel to the axis of rafter is 94.8 lb
The component of the force 
which is perpendicular to the axis of rafter
Therefore, the component of the force 
which is perpendicular to the axis of rafter is 284.7 lb

Find the components of the vertical force F= (0, -16) in the directions parallel to
Find the components of the vertical force F= (0, -16) in the directions parallel to and normal to the plane that makes an angle of θ = tan-1(√3) with the positive x-axis. Show that the total force is the sum of the two component forces. What is the component of the force parallel to the plane? What is the component of the force perpendicular to the plane? Find the sum of these two forces.

In this question, I'm asked to find P and alpha so that the
forces are a couple. I have found P and alpha, so my question is
related to finding the moment of the couple. In the solution, the
forces are broken down into x and y components, and the components
are multiplied by their respective perpendicular distances. Using
this method, the moment was found to be 272 Ncm. I was wondering
why it isn't possible to instead find the...
