Extracted text: A homogeneous block of height 0.4 m, width 0.3 m and weight 521 N is put on a rough horizontal surface and connected to a block of weight W through a massless inextensible string AD as shown. The string passes over a rough circular fixed surface and contacts it over the portion BC. The portion AB of the string makes an angle of 30 deg with the horizontal, and the coefficient of static friction on all contacting surfaces is u=0.4. Calculate the maximum value of W (in N) for which static equilibrium is maintained (answer correct to 1 place of decimal).
