Suppose you use an ideal pulley of the type shown in Figure 5.18(a) to support a car engine of mass 110 kg.

What would the tension in the rope be?
 N

### Block and Tackle Pulley Systems The diagrams depict three different configurations of block and tackle pulley systems, which are used to illustrate the mechanical advantage provided by these systems. #### Diagram 1: Single Pulley System - **Components**: - One fixed pulley attached to a support. - One movable pulley connected to the weight \(Q\). - **Forces**: - A single rope passes over both pulleys. - The force required to lift the weight (\(F\)) is equal to the weight (\(Q\)). - **Mechanical Advantage (M.A.)**: - M.A. of 2, meaning the system halves the effort needed to lift the weight. #### Diagram 2: Double Pulley System - **Components**: - One fixed pulley. - Two movable pulleys connected in sequence. - **Forces**: - The rope loops through both movable pulleys and the fixed pulley. - The force required to lift the weight (\(F\)) is one-third of the weight (\(Q\)). - **Mechanical Advantage (M.A.)**: - M.A. of 3, meaning the system requires one-third of the effort to lift the weight. #### Diagram 3: Triple Pulley System - **Components**: - Two fixed pulleys. - Two movable pulleys. - **Forces**: - The rope weaves through multiple pulleys, distributing the force. - The force required to lift the weight (\(F\)) is one-fourth of the weight (\(Q\)). - **Mechanical Advantage (M.A.)**: - M.A. of 4, meaning the system requires one-fourth of the effort to lift the weight. ### Understanding Mechanical Advantage The mechanical advantage (\(M.A.\)) of a pulley system is the ratio of the load force (\(Q\)) to the effort force (\(F\)). It represents how much the pulley system reduces the effort needed to lift a weight. In these diagrams: - **Diagram 1 (Single Pulley)**: M.A. = 2 - **Diagram 2 (Double Pulley)**: M.A. = 3 - **Diagram 3 (Triple Pulley)**: M.A. = 4 ### Applications of Block and Tackle Systems These pulley systems
