QI /
Brass rod diameter 6 mm is subjected to tension of 5 KN, the diameter change
by 3.6* 10 *mm the length of this rod is 50 mm and it increased by 0.098 mm.
Determine the Poisson's ratio?
Q2\
Prove that:
S.e = m .Gs
Q3/ Sample of steel has a diameter of 79mm was tested for tension. If
the applied load is 63.2kN and the elongation is 0.2mm
find :1- original length of the sample. 2- magnitude of the change in
diameter.
Take modulus of elasticity = 200 x 10' and Poisson's ratio = 0.3
