Question details

BTMM2153 STRENGTH○FMATERİALS Sooudd Four steel bars jointly support a mass of 15 Mg as shown in Figure Q3. Each bar has a cross- 11 7 μm/(m°C) and E-200 GPa when the sectional area of 600 mm. Assume a temperature increases 50°C, find; a) the load carried by Bar A and Bar D. b) the load carried by Bar B and Bar C.A0 c) Describe how the separation angle between Bar A, B, C and D will affect the elongation (10 marks) , 21.02 lerv (10 marks) of each bar due to increase in temperature Suggest few solutions to reduce the overall elongation of the bars shown in Figure Q3 (5 marks) L 7 15% 15° 15 Mg l Figure Q3 [Total: 25 marks] a tiy S d-)
