While most disk galaxies are observed to be warped, the mechanisms for the warping are not well understood. We explore warping caused by gravitational perturbations created by the passage of a distant galaxy (the 'intruder'). We propose that the intruder's effect on the disk galaxy can be explained in terms of pseudoforces that occur while the two galaxies interact. We carry out N-Body simulations with plausible interaction parameters that give significant warps having amplitudes comparable to those observed in some disk galaxies. The interacting galaxies have typical separations of 150-200 kpc and the intruder galaxy is moving at angles of 30, 45, 60, and 90 degrees relative to the plane of the disk galaxy. For each simulation we obtained integral-like shapes for the disk galaxy. (Simulations with other separations and interaction angles generated the other classifications of warps, called `feeble’ and `irregular.') Further observations of galaxies with these signature integral-shaped warps, located in the vicinity of massive neighbors, would support the existence of this mechanism.
