Theory of Structures A material is said to be perfectly elastic if None of these It does not regain its original shape at all It regains its original shape on removal of the load It regains its original shape partially on removal of the load None of these It does not regain its original shape at all It regains its original shape on removal of the load It regains its original shape partially on removal of the load ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A steel rod of sectional area 250 sq. mm connects two parallel walls 5 m apart. The nuts at the ends were tightened when the rod was heated to 100°C. If steel = 0.000012/C°, Esteel = 0.2 MN/mm², the tensile force developed at a temperature of 50°C, is 120 N/mm² 150 N/mm² 100 N/mm 2 80 N/mm² 120 N/mm² 150 N/mm² 100 N/mm 2 80 N/mm² ANSWER DOWNLOAD EXAMIANS APP
