java - LibGdx: How to make a body rotate in response to a linear impulse applied away from the center of the body? -

i heard calling applylinearimpulse body @ center not cause rotation, means applying @ other point should cause body rotate right? tried doing body still not rotate according fixture drawn box2ddebugrenderer. need provide additional setup rotation of body work in response applylinearimpulse? libgdx automatically take care of rotation result of forces/torque or have implement these kinds of rotations ourselves?
