Assume the members are pin connected at their end points. Take A = 200 mm2, and E = 200 GPa for each member. Use the method of virtual work.

How did you come up with the size of the rectangular cross section b = 16 inches and h = 24 inches in step 3 of this solution?

Part H dH = 320 mm Part H - There are 2 questions in this part Refer to your email from Tim which defined values of the different variables. Consider the shape below. It is made of solid aluminium (E = 70000 MPa). The shape can be considered as a rectangle 2dμ x dμ with semi circular portions top and bottom. 2d4 Question 22 Question H1 What is the second moment of area about the horizontal centroidal axis? You will not be able to enter your answer using exponential powers of 10 - eg if the answer is 3.456 x 106 you would need to enter 3456000. You must get both questions of this part correct to get marks. Question 23 Question H2 What is the second moment of area about the vertical centroidal axis? You will not be able to enter your answer using exponential powers of 10 - eg if the answer is 3.456 x 106 you would need to enter 3456000. You must get both questions of this part correct to get marks.

Report your answers to 2 decimal places in standard notation (no exponents) without units There are 12 inches in a foot, and 2.54 cm in an inch. A.) How many feet are in 200 meters? B.) How many meters are in 10,000 ft?
