An alumninum (E = 68.9 GPa) cylindrical tube has an outer diameter of 200 mm, a wall thickness of 7.5 mm, and an internal pressure of 5 MPa. It is subjected to a force with the axial and transverse components shown acting at the centroid of the free end of the tube 1. Verify that the tube meets the thin-wall criterion 2. Draw the left half of the tube, and show the equivalent force-couple system acting at the centroid of...
The single-story unbraced frame shown below is subjected to dead load, roof live load, and wind load Figure 1 shows the results of a first-order analysis relative to the columns of the frame. The axial load and end moment (also equal to the maximum moment in the column) are given separately for the different load cases (i.e., dead load, roof live load, and lateral wind load). All vertical loads are symmetrically placed and contribute only to the Mnt moments (i.e.,...
Sketch (qualitatively) the influence line for (a) the vertical reaction at C, (b) the moment at B, and (c) the shear at E. In each case, indicate on a sketch of the beam where a uniform distributed live load should be placed so as to cause a maximum positive value of the corresponding force/moment investigated. Assume the beam is fixed at F. Supports at A, C, and D are rockers (roller supports) E F 4 m iTm Sketch (qualitatively) the...
