A channel-section has the dimensions as shown. Consider a cantilevered beam subjected to an end force P. L = 100 cm a) iif cross-section las is used, determine its normal stress distribution. (a) (b) b) if you stack two las sections as a box, but leave a gap between them, two sections carry = loadings with the same distribution pattern. Try express the results. (C) 2ª L 2CM дом E 2ch weld

2. The height of the limit 5, relative to the compression zone needs to be calculated according to the assumption of

The beam supports the triangular distributed load shown below with Wmax=770 lb/ft. The reactions at A and B are vertical. 6 ft BI D 6 ft C 6 ft W B E 4.5 ft 4.5 ft
