A long steel rod is placed horizontally between two supports, one at each end. The rod bends a little in the center. Which property of this rod can be used to estimate how  much the rod should bend at the center? 1. Its Shear Modulus   2. Its Young's Modulus   3. All of these Moduli can be used to compute how much it bends.   4. Its Bulk Modulus.
