A force table is set up with two forces acting on a common point O. Force F₁ has a magnitude of 5.0 N and is directed at 30° measured anticlockwise from the positive x‑axis. Force F₂ has a magnitude of 8.0 N and is directed at 120° measured anticlockwise from the positive x‑axis.

Question Parts

( a )
Resolve each force into its horizontal (x) and vertical (y) components and obtain the resultant vector by component addition. State the magnitude and direction (angle from the positive x‑axis) of the resultant.
( b )
Verify the magnitude of the resultant obtained in part (a) using the law of cosines, noting that the angle between the two forces is the difference of their directions. Then verify the direction of the resultant using the law of sines.
( c )
Express the resultant vector found in part (a) as separate horizontal and vertical components (i.e., give Rₓ and Rᵧ).
( d )
If the angle between the two forces were increased to 150° while keeping their magnitudes unchanged, calculate the new magnitude of the resultant. Comment briefly on how the change in angle influences the resultant magnitude.
