3.3 – THEORY OF SYMMETRIC BENDING OF BEAMS In the questions below, select the correct answer. Name Email 1. If you know the bending normal strain at one point other than the centroid, then the bending normal strain can be found at any point on the cross section. True False None 2. If you the maximum bending normal stress on a cross section, then the bending normal stress at any point on the cross section can be found for a linear-homogenous material. True False None 3. A rectangular beam with a 2-in. × 4-in. cross section should be used with the 2-in. side parallel to the bending (transverse) forces. True False None 4. The best place to drill a hole in a beam is through the centroid. True False None 5. In the formula y is measured from the bottom of the beam. True False None 6. The formula can be used to find the normal stress on a cross section of a tapered beam. True False None 7. The equations and cannot be used for nonlinear materials. True False None 8. The equation can be used for nonhomogeneous cross sections. True False None 9. The internal shear force jumps by the value of the applied transverse force as one crosses it from left to right. True False None 10. The internal bending moment jumps by the value of the applied concentrated moment as one crosses it from left to right. True False None Do you have any comments or suggestions?
