"The Function of Inclined Plane" Tools and Machinery PPT Courseware 3

1. Understanding the Incline

A simple machine like a wooden plank stretched over a car cabin is called an incline.

2. Explore the role of inclined planes

Question: Can beveled surfaces save effort?

Can we design an experiment to study this question?

experiment plan

My question: Does the bevel save effort?

My guess: The bevel saves effort.

Experimental materials: inclined plane, different weights, dynamometer.

Experimental steps:

1. Set up the experimental device.

2. First measure the force that directly lifts the object, and then measure the force that lifts the object along the incline.

3. Change the weight of the object and repeat step 2.

4. Discuss and organize experimental findings.

3. Study slopes with different slopes

Does the force used to pull an object along an incline differ depending on the slope? Can we design an experiment to prove it?

Experimental results:

The longer the slope, the smaller the slope and the greater the effort savings;

The shorter the slope, the greater the slope and the less effort.

Thinking: When a person encounters an uphill slope while riding a bicycle, how can he ride with less effort?

Walk uphill as much as possible, which is an S-shape. Walk back and forth to the left side of the road, and then to the right side of the road. The more distance you cover, the smaller the walking angle is, which saves effort.
