Maxwell element A in creep at a constant stress of 10,000 Pa exhibits a total elongation of 0.65 strain units after 100 h and a permanent set of 1.00 unit on removal of the load after a total of 250 h. Now a generalized Maxwell model made up of elements A, B, and C is constructed. B has twice the spring modulus and one-half the relaxation time of A, whereas C has one-half the spring modulus and twice the relaxation time of A. If a sudden elongation of 1.80 units is applied and held constant on the generalized Maxwell model, what stress will be exerted by it after 100 h
