a: By checking if the individual strains are within a range of ±20 percent of their mean value at σb, at the first preloading cycle b: By checking if the individual strains are within a range of ±20 percent of their mean value at σa, at the first preloading cycle c: By checking if the individual strains are within a range of ±20 percent of their mean value at σa, at the last loading cycle d: Not necessary to check centering of the specimen.

4. On a concrete specimen of cylindrical compressive strength 27 MPa, longitudinal strains at basic and upper loading stress are 0.0001 and 0.0003. static modulus of elasticity will be

a: 27000 MPa b: 90000 MPa c: 30000 MPa d: 135000 MPa
