What material from the table will allow for the lightest beam with a tubular circular cross section:

Now, reconsider the tubular circular cross section case for an application where the inside diameter of the tube r_2 is specified by the design (such as a telescoping drive shaft or a crane boom), and r_1 is chosen to meet the design specified deflection. What material minimizes the mass:

What material from the table will allow for the lightest beam with a solid rectangular cross section

Which of the following properties are inconsequential to the response of an elastic perfectly plastic material?

Which of the following is the largest viable Poisson’s ratio,

For a typical metal, one should expect the shear modulus to be

If a bar of uniform cross section and ductile material is strained in a uniaxial tension test, would the observed engineering strain to failure of the entire bar be the same if a bar of different length were tested?

A ductile isotropic material has a Young’s modulus of 70 GPa and a strain hardening exponent of 0.5. At what value of strain might one expect the engineering stress to be maximum in a uniaxial tension test?

The slope of the uniaxial engineering stress – engineering strain curve can be used to determine which of the following

If an isotropic material has a large Poisson’s ratio, what can be said about its ratio of bulk to shear modulus:
