A rod of length 20mm is stretched to make a rod of length 40 mm. Subsequently, it is compressed to make a rod of final length 10 mm. Consider the longitudinal tensile strain as positive and compressive strain as negative. The total true longitudinal strain in the rod is _______1 AnswerA tensile specimen was deformed to a true strain of 0.405. The change in the gauge length was 5 mm. The final gauge length of the specimen, in mm, is: (-Gate metallurgical engineering 2014)1 AnswerConsider the singly reinforced beam shown in the figure below:At cross-section XX, which of the following statements is TRUE at the limit state? - gate civil 2017 1 AnswerThe value of true strain produced in compressing a cylinder to half its original length is Gate-20161 AnswerA sonometer wire of length 1.5 m is made of steel. The tension in it produce an elastic strain of 1%. What is the fundamental frequency of steel if density and elasticity of steel are 7.7 × 103 kg / m3 and 2.2 × 1011 N/m2 respectively ? - physics 20131 AnswerA wire of length L and resistance R is stretched so that its length is doubled and the area of cross-section is halved.
