A 30 kN weight is supported by means of a pulley as shown in the figure. The pulley is supported by the frame ABC. Find the required cross-sectional areas for members AC and BC if the allowable stress in tension is 140 000 kN/m² and in compression, determined by the method of Chapter 13, is 96 000 kN/m². Ans. 306 mm². 1-20.
