Results obtained from a tension test on a bar of uniform cross section 10 mm x 10 mm subjected to an axial pull of 8000 N were tabulated. The lateral dimensions of the bar were found to be changed to 9.9985 mm x 9.9985 mm while using a material having modulus of rigidity equal to 0.8 x 107 N/cm2. By determining the values for different moduli, identify the properties of material and establish the relationship between them. What changes will happen to the volume if the length of the bar is equal to 2.5 m? Based on the results obtained discuss how the elastic constants are related to the deformation of the bar?

Consider an electron beam of uniform circular cross-section with
a diameter of 1 mm. The electrons are accelerated from the cathode
to the anode, which are separated by 1 m. The electrons are
generated at the cathode and therefore have negligible velocity at
this position. The electrons accelerate at a rate of 108 ?/?2
between the cathode and anode. The current density at the anode is
104 ?/?2 .
Find the current density as a function of position between the...
