Resolve the force into components, one along P and the other along Q. The angles between P and Q are 70º.
P is in the x-direction and Q in the y-direction. |
Sum up the Forces in the y-direction and then divide it by sin of the total angle. This is Q.
For P, sum up the Forces in the x-direction and then subtract it by force Q in the x direction. This is P. |

A force is defined by 3.5i+1.5j+2k. What is the angle that the force makes with the positive y-axis?
|
Take the magnitude of the 3 points. Then use the Resolution of Forces: cosøy = Fy / IFI

|
Adding and removing Forces to a beam. What moment is needed at a certain point that would keep a reaction at another point the same?
|
The reaction at the other point is irrelevant. Take a moment of the forces being added and subtracted.

|
Three coplanar forces are on a steel plate. 2 of the forces are known with their angles. 1 force is not known and its angle is not known. What is its angle?
|
Sum up the forces in the x-direction and solve for F.
Sum up the forces in the y-direction and solve for F. Set the 2 F's equal to each other and solve for ø. |
