The problem is given in units of pounds and feet, so you should do your calculations in the same units.goldfish9776 said:
A resultant force is the single force that represents the combined effect of multiple forces acting on an object. It is the net force that results from the vector sum of all the individual forces.
The direction of a resultant force is determined by the vector sum of all the individual forces acting on an object. This can be calculated using trigonometry and the principles of vector addition.
Yes, the direction of a resultant force can change if the magnitudes and/or directions of the individual forces acting on an object change. The resultant force will always point in the direction of the vector sum of the individual forces.
If the resultant force is zero, it means that the vector sum of all the individual forces acting on an object is equal to zero. This can occur when the forces are balanced and cancel each other out, resulting in no overall movement or acceleration of the object.
The direction of a resultant force is typically represented by an arrow pointing in the direction of the force. The length of the arrow can also represent the magnitude of the force, with longer arrows representing larger forces and shorter arrows representing smaller forces.
