The victory of the weak/tug of war competition/comparing whose strength is stronger - Science Museum exhibitions exhibition items plan
What It Shows
The victory of the weak/who is stronger than the others/tug of war competition, where the audience selects poles of different heights for tug of war competition. Through personal experience, the magic of the lever principle is visually demonstrated to the audience.
Science Behind It
The principle of leverage: "Give me a fulcrum, and I can lift the entire earth!" Archimedes discovered the principle of leverage, which states that "when two heavy objects are balanced, their distance from the fulcrum is inversely proportional to their weight
source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. In physics, a hard object that can rotate around a fixed point under the action of force is called a lever. A pulley is a deformed lever, the essence of a fixed pulley is an equal arm lever, and the essence of a movable pulley is a labor-saving lever where the resistance arm is half of the power arm. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. The fixed point around which the lever rotates is called the fulcrum (O), the force that drives the movement of the lever is called the power (F1), and the force that hinders the movement of the lever is called the resistance (F2).
Description
Exhibition items is a vertical exhibition stand similar to clock hands, consisting of pointer models, ropes, rulers, indicator lights, sound systems, etc. A pointer model is erected in the middle of the booth, and poles are set on both sides of the pointer. A rope is connected to each pole, and the position of the rope on the pole can be adjusted. Set an angle ruler above the pointer.
After adjusting the position of the ropes on both sides, grab the ropes at both ends and compete in tug of war. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Reminder: During the competition, both sides should try to pull the pointer towards themselves and observe the angle change indicated by the needle tip above,
How to Take Part
1. Participate in the tug of war competition by adjusting the position of the ropes on both sides and grabbing the ropes at both ends;
2. Pull the pointer towards yourself until
3. Adjust the position of the rope and repeat the process
