For an ASTM 25 cast iron, a) find the factors of safety using the BCM and MM theories,
b) plot the failure diagrams in the GA, GB plane to scale and locate the coordinates of the stress state, and
c) estimate the factors of safety from the two theories by graphical measurements along the load line.
Use the appropriate parameters for the specific problem from the table below:
Problem Number 0x(kpsi) y(kpsi) Txy (kpsi)
5-21 15 10 0
5-22 15 -50 0
5-23 15 0 -10
5-24 -10 -25 -10
5-25 -35 -13 -10
