Question
Suppose you use an ideal pulley of the top shown in figure 5.18(a) Play to support a car engine of mass 150 kg.
(a) what would the tension in the rope be?
n?
what force must the ceiling supply ,assuming you pull straight down on the rope ? Neglect the pulley systems mass.
n (upward) ?
Transcribed Image Text:The image illustrates three different pulley systems, each showing a distinct mechanical advantage (MA). Here's a detailed breakdown of each diagram:
**Diagram (a):**
- **Setup:** A single movable pulley attached to a fixed point.
- **Mechanical Advantage (MA):** 2
- **Tension (T):** Applied upwards with two sections of the rope supporting the load.
- **Load:** Represented by the weight (w), shown at the bottom.
**Diagram (b):**
- **Setup:** Two movable pulleys in a combination.
- **Mechanical Advantage (MA):** 3
- **Tension (T):** Distributed among three sections, supporting the load.
- **Load:** Indicated by the weight (w).
**Diagram (c):**
- **Setup:** A system with three movable pulleys.
- **Mechanical Advantage (MA):** 4
- **Tension (T):** Applied across four sections, offering a greater lift for the same input force.
- **Load:** Presented by the weight (w).
**Figure 5.18:** Demonstrates the relationship between the number of pulleys, tension distribution, and mechanical advantage, illustrating how pulleys can reduce the force needed to lift an object by distributing tension across multiple segments of rope.
Expert Solution
Step 1
