Problem 1.

The cantilevered tube shown in Fig. 1 is to be made of

2014 Aluminum Alloy. We wish to select a stock-size

tube from Table 1 (attached) using a 20 x 4 mm

dimension and a design factor n=4. The bending load

is F = 1.75 kN, the axial tension is P = 9.0 kN, and the

torsion is T=0 N. m.

Note the variable na is the factor of safety using the

distortion theory. We will talk about this later but for

now you want to compute the von Mises stress, o', and

compare that to the yield strength of the material.

Problem 2.

Create a SW finite element model of Problem 1.

a. Show images of the deformed configurations.

b. Include stress contour plots for the normal and shear stresses in the cross section near the

location where you expect maximum stress.

c.

Compare your solution for the maximum bending and shear stress using the percent

difference.

d. Provide an engineering drawing using third angle view.

Make sure your solutions are clearly highlighted with a box or some other method to

make them stand out.
