Engineering Mechanics Practice Test 5

1. As space trusses are used in bridges. When the bridges are extended over long routes or distance then:

2. Normal force is equal to _______________

3. Change in the shear is equal to ____________

4. In a roof supporting space truss, the load is transmitted as:

5. The couple in the beam is simplified easily by the help of right hand rule. But the forces simplification is not possible as there is no such system of rules so that the forces can be simplified.

6. In the making of the shear force diagram or the bending moment diagrams, one method is used, distributed load. In this the distributed load will be considered positive if ____________

7. For the determination of the forces at the supports which part is to be considered in the calculations?

8. The shear diagram will jump upwards if there is __________

9. According to the _________ law of Newton the loadings at the sections must act opposite to the forces applied.

10. The internal loading can be found by _________________
