Acast iron part is subjected to principal stresses of σ1 = 480 mpa, σ2 = 210 mpa and σ3 = 0. by utilizing a universal testing machine (utm) the cast iron material was found to have a yield strength of sut = 215 mpa and suc = 750 mpa. compare the factor of safety using cmt and mmt.

does anyone know the n factor equations for cmt and mmt? this is an easy question i just can't seem to find the formulas.

Heena wants to measure the volume of a ball that is 24 cm across. how should she set up her equation?

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.
