You Want to Move Big Things. Let’s Make It Easy
Is it hard to lift or pull something? Maybe you need to move up, or lower, or tilt something heavy. That is where a kaldıraç helps. At Jimi (Jimi Technology Co., Ltd.), we know all about levers and smart machines. We help you move things at the push of a button. Today, let’s look at a special lever called a third-class lever. What happens when the force is on an angle? Read on! You will see how this helps you, step by step.
A Third-Class Lever: What Is It?
A third-class lever is a simple machine. It helps us move loads fast and far.
- Fulcrum: This is the turning point. Think of your elbow.
- Effort: This is where you push or pull. Think of your hand.
- Yük: This is what you want to move. Think of a ball or stone.
In a third-class lever, the effort goes between the fulcrum and the load.
Examples:
- Your arm (when lifting a ball)
- A fishing rod
- Tweezers
- A broom
Chart: Third-Class Lever Parts
| Part | What It Is | Where To Find It |
|---|---|---|
| Fulcrum | Pivot point | Elbow or hand grip |
| Çaba Gücü | Where you push | Biceps, hand, thumb |
| Yük | What moves | Object, fishing lure, dust |
This lever gives speed. You move the load a long way, with little movement at your hand. But, you need to use more force than the load. This is called mechanical disadvantage.
Why Angle Matters
Have you ever tried pushing a door not straight but at a slant? It feels harder, right? The angle at which you push or pull a lever changes the result.
- If you push straight (90°), it is easy.
- If you push at an angle, it gets harder.
So, why? Because only part of your push helps.
Bunu parçalara ayıralım:
- Perpendicular Force: This is the helpful force. It makes the lever turn.
- Parallel Force: This does not help turning. It just pushes along the lever.
Real-world tip: Always try to push close to 90°. But, sometimes you can’t. Maybe the fish is not pulling straight, or your arm moves. Then, the angle is less. Now, only a part of your force is working.
How Do We Figure It Out? Key Formulas (Made Easy)
Torque is the turning force. We need torque to make things move.
When the force is not straight, we use this:
Torque (τ) = Force (F) x Lever Arm Length (r) x Sine of the Angle (sin θ)
- τ = F × r × sin(θ)
Table: Quick Formulas for Levers
| Idea | Formula | Anlamı Nedir? |
|---|---|---|
| Torque (Angle) | τ = F × r × sin(θ) | Turning force when force is angled |
| Perpendicular Force | F_perp = F × sin(θ) | Only this part makes it turn |
| Mechanical Adv. | MA = Load / Effort | How easy/hard a lever feels |
Let’s see an easy example:
You push a mop (the lever) at 30° from straight up. You use 10 Newtons (N) of force. The mop handle is 1 meter long.
- The perpendicular part of your force:
10 N × sin(30°) = 10 N × 0.5 = 5 N
- The torque:
τ = 10 N × 1 m × 0.5 = 5 Nm
Only “5 N” of your push goes into turning the mop! The rest is wasted.
Why Is Mechanical Advantage Low With Angles?
A third-class lever already gives you speed, not strength.
- MA (mechanical advantage)
- If you push at an angle, MA drops again.
For example, if your angle is 60°:
- sin(60°) ≈ 0.87.
Only 87% of your force helps.
If your angle is 10°:
- sin(10°) ≈ 0.17.
Very little help.
List: How to Get the Most From Your Lever
- Push as close to 90° as you can
- Make your lever long (longer = more effect)
- Hold your load near the end
- Use tools that adjust for angle, like a flexible broom
Real-Life Examples: You See These Every Day
Your Arm Is a Lever
- Your elbow is the dayanak noktası
- Biceps pulls (the effort)
- Hand holds a ball (the load)
As you lift, your muscle pulls at angles. At 90°, you are strongest. When your arm is straight or bent a lot, the angle is less, and it feels harder.
Fishing Rods, Brooms, Tweezers, and Bats
- Fishing rods: When a fish pulls sideways, you get max bend (torque). Pulling straight down gives less.
- Brooms: The angle of your hands makes sweeping easier or harder.
- Tweezers: Only the squeeze that goes “across” the handle pinches tight.
- Baseball bats: The way you hold changes the speed and power at the tip of the bat.
Table: Everyday Third-Class Lever Uses
| Tool | Fulcrum | Effort | Yük | Angle Affects? |
|---|---|---|---|---|
| Arm | Elbow | Biceps | Hand | Yes |
| Fishing Rod | Handle | Hand/Wrist | Fish | Yes |
| Broom | Bottom Hand | Top Hand | Dust | Yes |
| Tweezers | Eklem yeri | Your squeeze | Small thing | Yes |
| Bat | Grip/Hands | Shoulder muscles | Ball | Yes |
