I. Fill the letter of correct answer in the brackets. (3 items, 3 points per item, a total of 9 points) Score 1. The internal forces of a statically deteminate structure may be influenced by: A. the size of member cross sections B. the shape of member cross sections C. the length of members D. the material of members Answer. ( 2. The number of zero-force members in the following truss is: А. 1 В.3 С. 5 D. 7 Answer: ( 3. The most important different between arch and beam is that: A. the shape of the member axis B. whether the structure produce horizontal thrust or not under the action of vertical loads C. the magnitude of member's bending moment and shear force D. whether the structure have axial forces or not Answer: ( II. Iftrue, write T' in the brackets. If false, write 'F' in the brackets. (3 items, 2 points per item, a total of 6 points) Score 1. The order of internal force analysis for a statically determinate structure should be opposite to the geometric construction order. ( 2. The temperature changes, support settlements do not induce internal forces in a statically deteminate structure. ( 3. The load applied on the subsidiary portion of a statically determinate multispan beam produces no reactions and internal forces in the main portion of the beam. ( I.
