Activity 5.6 Physical Property Analysis Questions for Aluminum Object One Directions: Complete the calculation by hand. Show all work below and select the appropriate answer based on your calculations. Check your work using the 3D modeling software. If your answers differ, explain why you think they are different where appropriate. 1.       What is the volume of the part? A.      1.875 in.³ B.      1.125 in.³ C.     1.375 in.³ D.     2.125 in.³ SHOW WORK:                  2.                                                       What is the density of aluminum in grams per cubic centimeter? (This may require research. Be sure to document your source.)  2.700 g/cm^3 3.                                           What is the density of aluminum in pounds per cubic inch? Show your work including all conversion factors.   0.0975 lb/in^3 4.                                           Find the mass of the object (in pounds-mass) if it is made

Activity 5.5a CAD Model Features Part 1 Conclusion 1.          What 3D CAD functions could be used to create a wire coat hanger? We can use sweep after drawing line and circle for thickness of wire on a plane starting. 2.          For each of the following, sketch a 2D shape and an axis of rotation that you could use to model each of the following solid forms using the Revolve function within 3D modeling software. Dimension each sketch and indicate the axis of rotation that you would use. You may use software to check your answers. a.          A solid cylinder with a diameter of 3.5 in. and a height of 7 in. Be sure to dimension the shape. Dotted line is axis of rotation. b.          A solid sphere using the Revolve function. What rotation angle would you use? rotate at 360 degrees 3.          For each of the following, describe the solid form that would result from rotating the given shape about the axis of
