When I try to rotate a vehicle's wheel by using ApplyForce on and parallel to its edge, translational movement also occurs, so instead I have to set the shape's torque manually. Could an ApplyTorque function be added?

I guess I could add one, but it would just be this:

That is what I currently do. But is not ApplyForce also body->f += force;

If the offset is the zero vecter yes. If it's not, then it also generates a torque.

What is the reason that my using ApplyForce on and parallel to a circle's edge also causes translational movement? Is is that a pinjoint and springjoints are attached to its center?

Applying a force always causes linear acceleration, if the force is off center then it also generates a torque.
