I have not looked it up. It has just occured to me. What critter could cause most damage to humans and other animals if it was larger and still able to fly, squirm, swim or whatever it needs to do to attack its victims/prey? Disease or virus/bacteria/pathogen vectors do not count, neither does the use of tools like nuclear missiles.

Question 2 text 2. A rod, 1.60 m long, is pinned so it can rotate about an axis 0.500 m from the left end (thin, negligible mass rigid rod). This rod is on a level table top. Force one, a push applied to the left end of the rod, is perpendicular to the length of the rod, and has a magnitude of 20.0 N. Force 2, a push applied to the right end of the rod, is applied at an angle of 30.0 degrees outward from a perpendicular line at the end of the rod where the force is being applied, and has a magnitude of 35.0 N. Find the net torque (magnitude and direction) applied to the rod.
Question 2 answers
9.42 N*m, clockwise
29.6 N*m, Clockwise
17.8 N*m, Counterclockwise
23.3 N*m, counterclockwise
