HELP ME WITH THE DIAGRAM PLEASE

Problem $5\mathrm{.}21$

For an ASTM $30$ cast iron,

$($a$)$ find the factors of safety using the BCM and MM theories,

$($b$)$ plot the failure diagrams in the ${}_A,{}_B$ 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:
