    杆件ABC在B点和C点受荷载作用如图所示,则固定端A的约束反力和反力矩分别为( )。[img=549x413]1802f402fc5e2d7.png[/img]
    A: Fx=0, Fy=600N, Fz=450N, Mx=-1350Nm, My=0, Mz=800Nm
    B: Fx=0, Fy=450N, Fz=600N, Mx=-1350Nm, My=0, Mz=800Nm
    C: Fx=0, Fy=600N, Fz=450N, Mx=-1350Nm, My=0, Mz=0
    D: Fx=0, Fy=450N, Fz=600N, Mx=-1350Nm, My=0, Mz=0
