Let's solve this step-by-step based on the image you've described. The worksheet asks us to identify the
type of simple machine associated with each object using the provided word bank.
Word Bank:
- lever
- screw
- pulley
- inclined plane
- wedge
- wheel and axle
Now, let’s analyze each image one by one:
---
1. Tongs (top left):
- Tongs are a tool that uses a
fulcrum (the pivot point) and two arms to lift or grip objects.
- This is a classic example of a
lever.
✔ Answer: Lever
---
2. Ramp (top middle):
- A ramp is a sloped surface used to move objects up or down easily.
- This is an
inclined plane.
✔ Answer: Inclined plane
---
3. Spear or Arrow (top right):
- A spear or arrow has a pointed end designed to cut or penetrate.
- This is a
wedge — a type of simple machine that splits or cuts materials.
✔ Answer: Wedge
---
4. Jar with lid being opened (bottom left):
- The jar lid is being turned with a twisting motion.
- This is a
screw, as the lid has threads that spiral around it.
✔ Answer: Screw
---
5. Crane (bottom middle):
- A crane uses a system of ropes and wheels to lift heavy loads.
- The pulley system allows the load to be lifted with less effort.
✔ Answer: Pulley
---
6. Steering wheel (bottom right):
- A steering wheel turns a shaft (axle) to control the direction of a vehicle.
- This is a
wheel and axle system.
✔ Answer: Wheel and axle
