400 400 Jok N 330 375 j central support diameter = 70mm x 5.5 mm wall thickness i) Using 270 electrodes, find the required weld length to attach central support to base ii) Comparing weld size to the wall thickness of tube, where is the likely point of failure in the connection.

Select an American Standard Channel shape for the following tensile loads: dead load = 54 kips, live load = 80 kips, and wind load = 75 kips. The connection will be with longitudinal welds. Use an estimated shear lag factor of U = 0.85. (In a practical design, once the member was selected and the connection designed, the value of U would be computed and the member design could be revised if necessary.) The length is 17.5 ft. Use Fy=50 ksi and Fu=65 ksi. a. Use LRFD. b. Use ASD.

Use an elastic analysis and determine the maximum load in the weld (in kips per inch of length).

using Figure 5-27, what is the advantage of the suspended type magnet over the other two types of magnets?
