Problem 2: A rigid block of negligible mass is supported by three symmetrically spaced rods as shown. Each copper rod has an area of 900mm2 and E=120GPA, and the allowable stress is 70MPa. The steel rod has an area of 1200mm2, E=200GPA and the allowable stress is 140MPA. Determine the largest load P which can be supported.

Problem 2: A rigid block of negligible
mass is supported by three
symmetrically spaced rods as shown.
Each copper rod has an area of
900mm2 and E=120GPA, and the
allowable stress is 70MPa. The steel
rod has an area of 1200mm2,
E=200GPA and the allowable stress is
140MPA. Determine the largest load P
which can be supported.
