Let's analyze the problem step by step. ### Structure Description: - The structure is a cantilever beam fixed at T. - The beam extends horizontally from T to S to U to R, then vertically down to Q, and then horizontally to P. - The horizontal segments are **SU**, **UQ**, and **QP**. - The vertical segments are **TS** and **RQ**. - The lengths are given: **TS = 0.5L** (vertical), **SU = UQ = QP = L** (horizontal and vertical). ### Question: **What is the bending moment at Q?** ### Step-by-Step Solution #### 1. Loading (Not Shown) - The image does **not** show any applied load (W), but the answer choices suggest there is a load at the end **P**. #### 2. Cantilever Beam Principle - For a cantilever beam, the bending moment at a section is the sum of moments due to all loads to the right (or left) of the section. #### 3. Bending Moment at Q - If a vertical downward force \( W \) acts at point \( P \): ##### The moment at \( Q \) due to load at \( P \) is: - **Distance from Q to P = L** - Moment at Q, \( M_Q = W \times QP = W \times L \) #### 4. Check the Options: - The correct value is \( WL \). ### Final Answer: **The bending moment at Q is:** \[ \boxed{WL} \] **So, select the option: \( WL \).**
