Chapter 7, Problem 7.46P

The copper shaft shown in Figure P7.46 consists of two cylinders w ith the following dimensions: — 10 mm, L2=5 mm, Dj = 2 mm, and D2= 1.5 mm. The shaft is insulated around its circumference so that heat transfer occurs only in the axial direction, (a) Compute the thermal resistance of each section of the shaft and of the total shaft. Use the follow ing value for the conductivity of copper: k = 400 W/m • °C. (b) Compute the heat flow rate in the axial direction if the temperature difference across the endpoints of the shaft is 30°C.

10−9. The state of strain at the point has components of   ϵx = −100(10−6),   ϵy = −200(10−6), and γxy=100(10−6). Use the strain transformation equations to determine (a) the in-plane principal strains and (b) the maximum in-plane shear strain and average normal strain. In each case specify the orientation of the element and show how the strains deform the element within the x−y plane.
