GATE Mechanical Engineering (ME) 2017 Shift 1 Solved Paper

A rectangular region in a solid is in a state of plane strain. The (x, y) coordinates of the corners of the un-deformed rectangle are given by P (0, 0), Q (4, 0), R (4, 3), S (0, 3). The rectangle is subjected to uniform strains, ϵ_xx = 0.001, ϵ_yy = 0.002, γ_xy = 0.003. The deformed length of the elongated diagonal upto three decimals places, is ________units.
