Suppose you use an ideal pulley of the type shown in image (a) in the figure below to support a car engine of mass 135 kg.
### Diagrams:
1. **Diagram (a):**
- Shows an ideal pulley system with Mechanical Advantage (MA) = 2.
- The pulley configuration consists of two sections of rope supporting the load.
- T represents the tension in each part of the rope.
- W represents the weight of the load.
2. **Diagram (b):**
- Shows an ideal pulley system with Mechanical Advantage (MA) = 3 .
- The pulley configuration consists of three sections of rope supporting the load.
- T represents the tension in each part of the rope.
- W represents the weight of the load.
3. **Diagram (c):**
- Shows an ideal pulley system with Mechanical Advantage (MA) = 4.
- The pulley configuration consists of four sections of rope supporting the load.
- T represents the tension in each part of the rope.
- W represents the weight of the load.
### Questions:
(a) **What would be the tension in newtons in the rope?**
\[ \boxed{\hspace{5cm} \text{N}} \]
(b) **What force in newtons must the ceiling supply, assuming you pull straight down on the rope? Neglect the pulley system's mass.**
\[ \boxed{\hspace{5cm} \text{N}} \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F296fef9a-c947-42b6-a55f-96737f4868cc%2Ffb110950-c364-4be3-a1db-3bd73552c9ef%2F4uccx4m_processed.png&w=3840&q=75)
