"The Function of Incline" Tools and Machinery PPT

Part 1: What is the function of the inclined plane?

Which method do you choose to move the barrel to the high platform?

People often set up a slope between a low place and a high place to move heavy objects from a low place to a high place. This slope is called an incline. Incline is also a simple machine.

How do we study whether inclined planes can save effort?

Notice:

1. Before use, check whether the dynamometer pointer is aligned with the zero scale.

2. Pull on the inclined surface at a constant speed and slowly.

3. Pull the dynamometer as parallel to the incline as possible.

4. During the pulling process, the line of sight should be consistent with the scale when reading.

The role of inclined planes PPT, part 2 content: Inclined planes with different slopes

By placing a wooden board on wooden blocks of different heights, you can make several slopes with different slopes.

Pull a heavy object up each of these inclines and use a dynamometer to measure how much force is used. Record the amount of force exerted on each incline.

Analyzing the experimental data, we find what role does the slope play? What are the different and similar functions of slopes with different slopes?

Slopes can save effort;

The smaller the slope, the less labor-saving it is, and the larger the slope, the less labor-saving it is.

The role of inclined planes PPT, the third part: Inclined planes in life

Make a right triangle out of paper and roll the slope of the triangle around a pencil. What do you find?

The threads on the screws are like the lines formed by pencil rolls, and the length of the threads is equivalent to the length of the slope. The denser the thread lines, that is, the smaller the thread spacing, the more horizontal the thread lines, and the easier it is to tighten the screws.

Now can you explain why the winding mountain road is built in an "S" shape?

A straight uphill road has a steep gradient, while an "S"-shaped winding road has a smaller gradient due to the extension of the distance, making the climb more effortless.
