Structural Analysis topics include: Simple trusses, joints method, zero force member, sections method, space trusses, frame and machines. Structural analysis is a scientific method that engineers use to predict how structures will behave under different types of loads. It's a branch of solid mechanics that uses simplified models for solids like bars, beams, and shells.  Structural analysis involves determining the effects of loads on physical structures, such as bridges, buildings, and aircraft. It uses mathematical and mechanical principles to determine the magnitude of internal forces... Show more

25 Questions

1. When the bridges are extended over long routes or distance then a rocker or a roller is used at the joints. As when the temperature is raised the elongations and the contractions of the joints part are not much affected if the rollers and rockers are used.
2. In case of bridge the load is transferred as:
3. Trusses lie in a single plane. And the calculations used to solve the forces are from vector math.
4. The free body diagram of which part of the section of the truss is made to make use of method of joints?
5. The free body diagram of which part of the section of the space truss is made to make use of the method of joints?
6. _________ trusses lie on a plane.
7. The joint in the trusses are generally formed by welding the materials at the ends of the trusses on a common plate. Which gives strength to the design. What is that plate called?
8. If the whole truss is in equilibrium then all the joints which are connected to that truss is in equilibrium. This is known as:
9. If two members of the structure (trusses) form a truss joint and there is no external force acting on that joint then the two members are called___________
10. Truss cannot be acted upon three force members. Because the truss in a single plane.
11. The rules which are used to design the trusses are having various rules. Of them one is that the smooth pins are not used to join the members.
12. Which of the following conditions are true to make the calculations easy?
First condition: We use the method of a joint to find the forces acting over the joints in the space trusses.
Second condition: In this, we start from the joint having at least one known force and at the most two unknown forces.
13. If a force applied at any point in its line of action and is still creating the same moment about any fixed point say P, then the force is said to be a sliding vector. What is the name of this property?
14. ___________ are used as support loads.
15. The forces obtained at the joints and the members of the machines are very important. They are used for:
16. We use the method of joints when the members on which the force to be found are few in number.
17. The transmission of the load on a certain type of a structure follow as from stringers to floor beams and then joints. Determine the structure.
18. What will happen if the three members are all perpendicular to each other? No external force is applied to them.
19. To design the trusses which of the following rules is followed?
20. There are no rules for the designing of the truss. But there are rules designing the bridges.
21. Method of section cuts the whole structure of trusses into a section and then uses the cut out portion for the calculations of the unknown forces. For this method, at most two forces must be collinear.
22. The zero forces are used to improve__________ of the structure.
23. When the bridges are extended over long routes or distance then _________
24. In a roof supporting truss the load is transmitted when ________
25. The free body diagram of which part of the section of the truss is made to make use of the method of sections?
