How to solve this question step by step 

**Problem 7.8** - Determine the values of the weight \( W \) and the support forces at \( A \) and \( B \). The pulleys are frictionless, and their weight can be neglected. The diagram shows a pulley system with the following components: 1. **Pulley System:** - There are two main pulleys labeled \( C \) and \( D \). - Pulley \( C \) is connected to a support at point \( B \). - Pulley \( D \) is connected to a weight labeled \( W \). 2. **Weights and Forces:** - There is a 400 lb weight hanging directly from pulley \( D \). - The weight \( W \) is unknown and is hanging from the extended pulley system. - Support at point \( A \) indicates a connection point on the ground. 3. **Connections:** - A rope runs through the pulleys, connecting them and supporting the weights. - Support forces need to be calculated at points \( A \) and \( B \). This setup typically requires solving equilibrium equations to find the unknown forces and weight, assuming ideal conditions of frictionless pulleys and negligible weight of the pulleys themselves.
