Description

"The Function of Inclined Plane" Tools and Machinery PPT Courseware 4

Put a wooden board between the carriage and the ground to form an inclined surface.

Place the object on this surface and push or pull it up along the surface.

This surface becomes one of the simple machines - the inclined surface.

What do you think the bevel is used for?

Research topic: Can inclined surfaces save effort?

Experimental equipment: spring scale, wooden board, hook code

Experimental steps:

1. Set up the slope device.

2. Measure the force required to lift the object directly.

3. Then measure the force of lifting the object along the incline.

4. Change the weight of the object and repeat the above steps.

5. Analyze data and organize findings.

1. Among the three inclined planes in the picture above ( ) is the most labor-saving.

2. The thread of the screw is a deformation of the bevel. Screws of the same thickness have denser threads when screwed into wood ( ).

A. The more effort B. The less effort C. Neither effort nor effort

3. Among the following items, the ones made using the bevel principle are ( ).

A. Seesaw B. Wrench C. Stair lift in shopping mall

4. As shown in the figure, use a dynamometer to pull the same object along two surfaces A and B to the same height. The reading of the dynamometer will be ( )

A. Same size

B. The reading is large when pulling on side A

C. The reading is large when pulling on side B
