2. You have an open square box beam with an outside height of 3.5 cm. Theinside dimension is 3.0 cm. A. What is the area moment of inertia of the beam?B. The beam is loaded 27′ cm from a clamped end and has a de?ection of 3 mm. The beam is made of aluminum with a modulus of Elasticity of 7×106 N/cmz. What is the load on the beam?C. How many signi?cant ?gures should your answer in 23 have? 3. Using the information from problem 2, what would be the de?ections withloads of 1000N, 2000N, 3000 N, 4000N and 5000N? Show the data in two columns with load in one column then de?ection in the other column.
