Solve under applied mechanics

Okay Jason🕵🏻‍♂️🥷🏻, let's break down this beam problem step by step.

The beam has a total length of $L = 2.2 + 2.3 + 2.3 + 1.2 = 8 \, \text{m}$.

• A point load $P_1 = 80 \, \text{kN}$ acts downwards at $x=0$.
• A uniformly distributed load $w = 10 \, \text{kN/m}$ acts downwards over the entire length ($0 \le x \le 8 \, \text{m}$).
• A roller support is at B ($x=2.2 \, \text{m}$), providing a vertical reaction $R_B$.
