1-The size factor, kb, for a specimen with a 3.4 inch diamter is....... ?

2-The size factor, kb, for a specimen with a 6.3 inch diamter is....?

Solution

Solution :

1)

3.4 inch = 86.36 mm

We have

Kb = 1.51*d^-0.157

Hence Kb = 1.51 *86.36^-0.157 =0.7499

2) SImilarly 6.3 inch = 160.02 mm

Kb= 1.51*160.02^-0.157 = 0.6806
