Considering only bending energy, use Castigliano's theorem to find the vertical deflection at point B on a fixed-fixed beam with P = 5 kN, L = 1.5 m, a = 0.5 m, b = 1 m, and flexure rigidity El = 34,000 Nm. Reaction forces and moments as a function of the load P are as follows: RA B P UW ME 356 Spring 2023 a b L = 0.74P MA = 0.22P RC = 0.26P Mc = 0.11P Mc MA P TRC Recall equation 4-31: = Si Fi = St (MOM) dx 1) What is the internal bending moment M and its derivative OM/OP as a function of P and x in section AB? 2) What is the internal bending moment M and its derivative OM/OP as a function of P and x in section BC? 3) What is the deflection at point B?
