1. Consider the axially loaded tapered bar with a three-element model below: a P Following the steps shown on pages 8 thru 12 in Moaveni, and assuming that t is the thickness of the bar and E is the modulus of elasticity, solve for: a) Values of nodal u,, for i=1,2,3,4. b) Values of elemental ¿(i), i=1,2,3. c) Values of elemental ♂(i), i=1,2,3. d) Values of elemental F(i), i=1,2,3. Let a = 0.2 m, 1 = 1 m, t = 0.2 m, E=2×10° Pa, P=2×107 N. 2 1.
