Construa um MOTOR MOVIDO A VELA (MOTOR STIRLING)

Summary

This script outlines a DIY tutorial on crafting a candle-powered engine, a complex yet fascinating project that can be accomplished with household items. It involves assembling a chamber using aluminum foil and a sardine can, creating a flywheel with CDs, and utilizing a balloon pump and fishing line for motion. The engine operates by the heat from a candle causing air to expand, pushing a bladder which in turn drives a piston. The tutorial also offers insights into the mechanics and suggests similar projects for further exploration.

Takeaways

• 🔧 The video teaches how to build a heat engine powered by a candle.
• 🏆 The engine design was inspired by a contest winner, Tiago Casella, from 2012.
• 📘 The construction process is based on the 'Manual do Mundo', a specialized guide.
• 🔗 The video credits a specialized channel run by Vagner for detailed tips on building the engine.
• 🛠️ The engine requires common household items and a few inexpensive parts like connectors and fishing line.
• ⚙️ Key components include two shower connectors, fishing line, a 2mm diameter drill bit, and hot glue.
• 🔩 The engine chamber is made by combining an aluminum can with a sardine can.
• 🔄 The engine's motion is maintained by a flywheel made from glued CDs.
• 💧 A 'bombril' (plastic bottle) is used to create a piston mechanism, with a fishing line acting as a connecting rod.
• ♻️ The engine operates on a cycle of heating and cooling, causing the piston to move up and down, thus generating motion.

Q & A

What is the main purpose of the video described in the transcript?

The main purpose of the video is to teach viewers how to build a candle-powered motor using easily accessible materials.

Who is Vagner and why is he mentioned in the video?

Vagner is the person behind a specialized channel about this type of motor. He is mentioned for providing valuable tips and for winning a contest in 2012.

What materials are needed to build the motor chamber according to the script?

To build the motor chamber, you need an aluminum can, a can opener, pliers, and white glue.

What is the role of CDs or DVDs in the motor construction?

CDs or DVDs are used to create the flywheel that maintains the motor's momentum.

What is the function of the fishing line with a diameter of 0.37 millimeters?

The fishing line is used to connect different parts of the motor and to create tension in the mechanism.

How are shower connectors used in the motor construction?

Shower connectors are used to extract metal pieces that are later used as components in the motor's assembly.

What is the purpose of the Bombril glue mentioned in the script?

The Bombril glue is used to create a piston by making a spiral with a fishing line and attaching it to a clip.

How is the balloon's bixiga used in the motor's construction?

The bixiga of a balloon is used to create a valve mechanism that helps in the movement of the motor's piston.

What is the function of the 'virabrequim' in the motor's operation?

The 'virabrequim' acts as a crank that converts the linear motion of the piston into rotational motion for the motor.

How does the motor's operation cycle work?

The motor operates in a cycle where the heated air from the candle expands, pushing the piston up, and then cooling down, causing the balloon to contract and pull the piston back down.

What additional projects are suggested at the end of the script?

The script suggests building a candle-powered boat and an electric motor powered by a battery as additional projects.
