What is the dimensional formula of Young\'s modulus ......??? |
|
Answer» Wlc Ishu ?? Thanks Aman.....? Youngs modulus = ML^-1T^-2 Thanks yaar.... Young\' Modulus = stress/strain = F/A×e/l =ma/A×e/lWhere, F is force, A is area of cross section, e is elongation, l is actual length, a is acceleration, m is mass.By their units,Y= [(Kg×m/s ki power 2)]/[(m)ki power 2×m/m)]Y=(kg×m)/(m ki power 2 × s ki power 2)Y=kg/m×s ki power 2Therefore, dimensional formula of young\'s modulus is [ML^S*].《where ^ = -1 and * = -2.》☺☺ |
