The shown beam is loaded by an eccentric force P that is acting at a height of $10$

mm from the base. The beam has the shown cross section. Knowing that the

member is made of cast iron that has the maximum allowable stress in tension $\backslash$sigma $\_($all $)$t

$=40$MPa, and the allowable stress in compression

$\backslash$sigma $\_($all $)$c$=140$MPa, determine the maximum

allowable force P$.$
