#3. The distributed load w is supported by three suspender bars as shown. AB and EF are made of aluminum and CD is made of steel. If each bar has a cross sectional area of 450 mm*2, determine the maximum distributed load w (kN/m, ) so that an allowable stress of 180 MPa in steel and 94 MPa in aluminum is not exceeded. Use Est = 200 GPa and Eal = 70 GPa. Assume ACE is rigid. 1.5 m 1.5 m 'B 'D 'F al st al 3 m

As described in the Data and Results part of , all tables and graphs must have descriptive information such as titles, column or row headings, units, and axis labels, and data points must be clearly marked. All figures must be numbered and have a descriptive title. The figure number and the title should be placed below the figure. All tables must be numbered and have a descriptive title as well. However, for tables, the table number and the title should be placed above the table. The relationship between a spring force and its deflection is given in the table at the top of the next column. Plot the results using engineering paper and incorporating the ideas discussed in this chapter.

Q1 / Read the passage carefully and then answer the questions: There are two buildings that can be referred to as giant constructions in the world. The Petronas Towers were the tallest buildings in the world, which were opened in1999. With a height of 452 meters, the slender twin towers, like thin pencils, dominate the city of Kuala Lumpur. At the 41th floor, the towers are linked by a bridge, symbolizing a gateway to the city. The American architect Cesar pelli designed the skyscrapers with eight point star shape with an Islamic influence to reflect the Muslim culture of Malaysia. Also, The Millau Bridge was opened in 2004 in southern France. It reaches over 340m at the highest point. Described as one of the most breathtaking beautiful bridges in the world, it was built to relieve the problems caused by traffic passing from Paris en route to Barcelona in Spain. Designed by the British architect Norman Foster, it was built to withstand the most extreme seismic and meteorological…
