What is the variation to which the tension testing machine must be sensitive?

(a) 1/250 of the registered load

(b) 1/100 of registered load

(c) 1/500 of registered load

(d) 1/200 of the registered load

The question was posed to me by my school principal while I was bunking the class.

My doubt is from Aircraft Materials in section Testing Aircraft Materials of Aerospace Materials & Processes

Answer 1

The correct option is (a) 1/250 of the registered load

The best explanation: To obtain an accurate result, it is important for the test machine to be in appropriate condition. One of the important conditions is for a load being applied, the test machine must be sensitive to a variation of 1/250.
