100 KV 70 kN/m A t. 2m RB 4m 4m Ro Total distributed load on bearn = 50 +20 = 70 kN/m. (i) Marimum the reaction at Ĉ occurs when the point load placed att Apply (m) - 100 X10 + 70 X10X5 - Rex820 =0 =) Rp = 5607.5KN .. Maximum reactions at point B = 562.5 kW option (C) is correct. (ii) Maximum the sheas atė Ro ==Rp + 100+ 70xlo ---562.5 +809 = 937.SKN :: SF) c = 237.5 - 70x 4 = -425 kW place the lookN load atc, Rex 8 – 100x4.- 70x10x5 -0 5) Re = 487.5 kW -) Rp = 100+ 70X10 –487.5 = 3/2.5 the sheas, SFC = 3/2.5- 70x4 = 327.5 kn .: ophon), e) in conreet.
