The field of engineering is huge and touches nearly every aspect of our lives. You can share this fascination with your friends and family by watching a video on “Engineers Are Cool.” It features great pictures and fast-paced audio. You can also download a free printable version of the article.
Rube Goldberg machines
If you’re interested in the work of USA engineers, you might enjoy learning about Rube Goldberg machines. These complex machines start with the end of the chain reaction, and then work backwards to discover the action that will lead to the end. For example, flipping a light switch might require the user to decide how to push up on the switch before the light turns on. The next movement would then cause the previous movement to cause the next action.
Rube Goldberg machines were used as a classroom activity by prospective science teachers, and are a great way to teach science concepts. They can teach students about the incline plane, friction force, push and pull forces, equal arm scales, momentum, and torc.
Building a high-functioning robot
The brain of a robot is the control system. This controller system must determine how the robot moves and how to perform different tasks. It should also define its internal and external communication systems. It should also have control over the manipulator and end effector. There are two ways to control a robot: through a user interface or through task programming.
A robotics engineer is an individual who is trained to build and program a robot that can perform a range of tasks. These engineers will often work with stakeholders to understand the scope of a project and to identify its requirements. They will then draft designs for robots and test them to make sure they can perform the task efficiently. The design process may involve various fields, including mechanical engineering, computer programming, and artificial intelligence. Once the robot is built, engineers will also work to troubleshoot problems that may arise as it begins to perform its tasks.
Building a fingerprint scanner for your garage door
If you are looking for a way to open your garage door with fingerprint authentication, you should consider building a fingerprint scanner for it. Fingerprint scanners are becoming more popular, and are becoming easier and cheaper to build. Fingerprint sensors allow you to unlock your garage door without having to worry about your car. Fingerprint scanners work with your garage door’s sensor system, which means that you can unlock it even if you don’t have a smartphone.
To build a fingerprint scanner, you need a few parts. You’ll need an ATmega328 and a fingerprint sensor. The ATmega328 will be mounted outside your garage, in a 3D printed enclosure. Next, you’ll need to connect the fingerprint sensor to a button on the garage door. Alternatively, you can also run the wires from your garage’s internal button into the outdoor module.
Designing playground equipment
A good playground design starts with safety. The location of playground equipment is vital to prevent injuries. This means that the surface must be shock-absorbing. The Critical Height of a surfacing material is proportional to its thickness, with a deeper material being more shock-absorbing than a thin one. In addition, the safety surfacing material should be installed so that it is beneath the Fall Height of playground equipment.
Designing playground equipment requires engineers to account for the needs of children with different abilities and preferences. This type of design requires balancing the safety of playground equipment with the child’s need to explore and take risks. To be inclusive, play events must appeal to children of all abilities and should challenge children on their own developmental level.
Creating rides and attractions at theme parks
There are many factors to consider when creating rides and attractions at theme parks. From the budget to the location, theme parks have different needs than standard amusement parks. In order to be successful, a park’s rides and attractions should include a strong theme. Thematic attractions should involve associations with the theme park’s location, storyline, characters, and objective.
First, consider the layout of the ride. It will determine how it flows through the park. Taking into account the length of the ride, the thrill factor, engineering, structural considerations, and incorporated points of interest is essential. It’s also crucial to determine the capacity of the ride. Capacity refers to how many people can ride at one time, and this is an important factor when deciding the amount of money you’re willing to spend on a ride.
