Week 1 Challenge

1A:-1.Aim to find the most efficient gravity loads taking truess in given figure's

2.Conclusion that figure A(pratt trusses) is more efficent for gravity loads ,than figure B(Howe trusses).

3.Resulting that figure A is most efficient.

2A:- 1.Aim to Draw the Bending moment and Deflection shape for the given figures

2.Have submitted in image form for this Question.

3A:-1.Aim to find out moment of interia and weight of given section in the figure

2.Result are given the image form for this Question.

4A:-1.Aim to Calculate the load on the Interior beam & girder ,Exterior beam & girder.

2. Calculation in image form for this Question

5A:-1. Aim to Calculate the Length of the bridge at 40'c and it's length as the bridge is made of steel trusses.

2. Conclusion is that the beam is made of steel trusses ,so it have its thermal expansion, a metal bridge are build up form serveral section's.

3. which have air gap's between them ,in order to allow thermal expansion functions Due to temperature's changing accroding to sessions.
