No one can answer until you define 'lines of force'. We know that electric and magnetic fields interact. Their relationship is represented in Maxwell/s equations. As far as we know, no other fields or forces interact. You could draw lines or surfaces representing electric and gravitational fields, and those lines could certainly intersect, but the intersections would have no particular significance.

Let's think about it. Force can be though of as a vector. When acting on an object, it originates at one point and terminates at the other. So, when there are two or more forces acting on a single object they originate or terminate at a common point making a resultant force (the sum of all the forces acting on the object), so if the two forces do happen to intersect, then they are either not in the same plane or acting on different objects or both.
If you think, for example about an incline plane problem where a cart is moving downward. There are variouse forces acting on the cart, the normal force pushing the cart up meets the gravity force pushing the cart down, the friction force going up the incline and the initial force that "the guy at the top" gave to the cart down the incline. Normal force and friction force seem to want to intersect, but they don't, because they meet at a 90 degree angle. So, to answer your question in a definit manner, I would say: "No!"
However it depends on the branch of physics your are in.

Intersect:
TRANSITIVE VERB: 1. To cut across or through: The path intersects the park. [See source.]

No, one force vector cannot "cut across or through" another. As vectors (i.e., "lines of force"), forces can be added, subtracted (which is just another form of adding), or projected (e.g., V cos(theta) = v, where v is the projected V vector.).

Represented by arrows acting on the same body or object, you would never see one force arrow actually cross another force arrow. If you end up with a graphic having crossed vectors, you'd best go back and check your work.

Force vectors can touch, but never cross. Touching (head to head, or head to tail) represents subtracting or adding two vectors. Such subtraction or addition gives rise to a third vector (the resulting vector) that has both magnitude and direction. Thus, when two forces act on the same body, for example, the two force vectors will be head to head or head to tail (depending on the directions of the two forces) and give rise to a third force and commensurate force vector, which might be called the net force if there were no other forces to consider.

Not exactly sure what you mean... but sure you can apply 2 forces with different directions to the same object, their lines of action would intersect. The net force seen by the object would be the vector sum of all forces applied.

If two forces intersect, I believe the result is a new vector. Imagine two ocean waves converging before they reach shore to make a bigger single wave with a given direction. There's a formula, but it's been a while since I took statics and dynamics.

the elementary property of magnetic field strains is that the tangent at any factor to the line represents the process magnetic field at that factor. by means of this actuality, no 2 strains ever intersect one yet another, in the event that they intersect on the factor of intersection, that's obtainable to entice 2 tangents indicating 2 instructions for the sphere at a factor it is bodily absurd. it is why the strains of rigidity by no skill intersect one yet another whether close they could come.

yes, if they couldn't there would be no collisions
