14. A frame with tension-only diagonal braces resists a horizontal wind load of 15 kips acting to the right, as shown. What is the internal tension in each brace? 11. Wherever a hinge or pin exists in a structure, there can be no A. shear. B. moment. C. tension. A. Brace 1·0,brace 2 =21.2 kips B. Brace 1 0.6 kips, brace 2 = 10.6 C. D. kips Brace 1-21.2 kips, brace 2 =0 Brace l=15.0 kips, brace 2.0 15. For the three-hinged arch shown, the borizontal thrust is equal to H. If the span length (L) is doubled, while the rise (h) and the load per lineal foot (w) remain the same, what will be the magnitude of the horizontal thrust? 12. A load of 1,000 pounds is supported by cables A and B as shown. What is the tension in each cable? t/m A. B. C. D. A = 500#, B 500# A= 500". B=866# A= 866*. B= 500# A. 866, B-866# v- A. H B. 2H C 3H D. 4H 13. What is the internal force in member BD of the truss shown? 15,000 + A. Zero B. 5 kips C. 7.5 kips D. 15 kips

Explanation / Answer

11) Option B is correct. If there is a hing/pin there moment will be zero, means it can not transfer moment effectively.
