Question

all T-Mobile 11:31 AM a mycourses.purdue.edu 16%(1-0, 2. Were there expectations that the bolt or the bar would fail first in each test? Explain 3. Is the ultimate shear strength the same value as ultimate tensile strength? Explan . What did you notice about the shape of the specimen after the test was completed? How did it change? 5. What is the difference between a single shear and double shear? 6. How to determine the shear resultant in single shear and double shear? 7. What is the deference between the shear failure of a connector and that of a tensile/torsional specimen? 8. How can the shear strength of a connector be determined? 9. Why does bulging (due to bending) occur in a shear test? Discussion In this section, discuss any discrepancies, problems incurred, experimental errors and validity of the assumptions. References (if any is used in the report) Provide adequate references for all data, resources acquired

Explanation / Answer

5. Single shear carries all load on one face while double shear carries it on two faces, so stress is lowere by a factor of 2 for a given load.

8. When designing the shear connectors the total shear strength provided between zero and maximum positive moment locations is the sum of the shear strengths of all the shear connectors in that region.

7. Failure of connector is due to bending while that of teansile specimen is due to tensile loading.

3.If the force is supplied in a horizontal direction on either side,the material tend to gain tensile stres.If the same force is supplied on the surface of the material tangentially, then its Angle of position changes and hence attains shear stress.
