1.	In universal testing machine, for a circular section specimen, the gauge length is taken to be _____________(a) 3.65 √A(b) 4.65 √A(c) 5.65 √A(d) 6.65 √A where A is the area of cross section of the specimenThis question was posed to me in unit test.The question is from Testing topic in portion Concrete Mix Design of Concrete Technology
Answer» Right OPTION is (C) 5.65 √A The explanation: It is the formula to find the GAUGE LENGTH when we have the area of the specimen in a universal testing machine.
