Question

Chapter 5 Problems 157 calculation, which may not involve the support reactions. Also, we include only the l rces included, as in Eq. 4-32 of Sec. 4-8. This e nothing in the complete vector with zero applied fo is allowed because the zero applied forces Consequently, are desired, then we need to include even the zero applied nodal forces at the beginning. however, we are able to solye for , only. If all nodal displacements 0 PROBLEMS IS -1. Analyze the beam in Fig. 521 by the metbod of consistent deformations. the reaction at center support b as redundant. (b) Use the internal moment at bas Assume constant E 20 ft 2 Fizure 5-21 . Determine the reaction at b in Fig. 5-22 by the method of consistent deformations. Assume constant E.Dre moent dg ron Figure S-12 S-3 Find the reaction at b in Fig. 5-23 by the method of consistent deformations. Assume constant E 1-1,000 in. 1,500 in 5-4. For the system shown in Fig. 5-24, determine, by the method of consistent deforma- actions exp for Ω with tions, the reaction at support e.
