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.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

explanation:

wheres the pic

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
