Solve reaction at B and C Solve T(x) and M(x) and draw its diagrams

The beam is subjected to a uniformly distributed load of $10 \, \text{kN/m}$ over its entire length. The total length of the beam is $L = 2.2 + 4.6 + 1.2 = 8 \, \text{m}$.
The supports are a roller at B and a pin at C. Since there are no horizontal loads, the horizontal reaction at C is zero. We need to find the vertical reactions $R_B$ and $R_C$.

Step 1: Calculate reactions at B and C.

The total downward force due to the distributed load is $F_{total
