Problem $3$: A beam ABCD consists of two segments $AB$ and $BCD$ that are pin connected at $x=4m.$ The beam is supported by a slider support at A and roller supports at $C$ and $D$ as shown in figure below. The beam is subjected to a triangularly distributed load on BC with peak intensity $q_0=75\frac{N}{m},$ a concentrated force $F=100$ N at $x=2m,$ and a concentrated moment $M_0=200Nm$ at D $.$ If $L_1=2m,L_2=4m,$ and $L_3=3m,$ determine:

a$.$ The support reaction at $A$

b$.$ The support reactions at D

c$.$ Internal forces at $x=5m$

Answer:

a$.A_x(N)=$

$A_v(N)=$
