Answer 1

2 t/m 6m zm 2 T/M JON uro-20t-m =0 According to comparability Condition ( 48 bueri + (46) Duet + (45) Due to - delovers = 0 -> eq zo T-m 10T UdL Deflection due to UDE: - zx64 324 SELET Substis tate all in above equation (1) Deflection due to 10T Deflection due to 20 T-m: A8 = M = 20x6 Defleclection due t Reaction Re: = 360 324 70 + 30 - 72 80 =0 . 72 RB = 1404 Rp = 19.5 T upward reaction at 'B'
