Description

"Skillful Use of Inclined Planes" Architecture and Simple Machinery PPT Courseware 4

1. What is a pulley block?

Combination of moving pulley and fixed pulley.

2. What are the advantages of pulley blocks?

It saves effort and can change the direction of force.

Think: How much force does it take to lift a heavy object?

Lift heavy objects with 1/2 force

Use 1/3 of the force to lift heavy objects

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

experiment plan

Experiment Name: Studying the Effect of Inclined Planes

Experimental equipment: Incline, 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 1.

4. Discuss and organize experimental findings.

Characteristics of the bevel:

Slopes can save effort. The smaller the slope, the less effort. The larger the slope, the more effort.

After-school exploration:

When a person encounters an uphill slope while riding a bicycle, how can he ride more effortlessly?

Operation:

1. What are the characteristics of the inclined plane?

2. Observe what other slopes there are in life
