In the bottom there is a uniformly-thick gate (1.6 m x 2 m) which is hinged at B and supported by a roller at A. The gate which has a weight of 10 kN can be opened by means of the cable at A. The density of the salt-water is 1.04 Mg/m". Determine the tension in the cable just before the gate opens.

A steel beam is fabricated from a W406 x 60 and two plates 10 mm x 500 mm which are welded to the ﬂanges of the wide-ﬂanged section as shown. The properties of W406 x 60 sections are also shown below. Determine the maximum bending moment which can be applied before any yielding of the material occurs.
