What is a real life example of a linear actuator?

Linear actuators have many real-life applications in various industries, including manufacturing, automotive, aerospace, robotics, and healthcare. Here are a few examples:

1. Electric windows in cars: Linear actuators are commonly used in electric windows of cars to move the window up and down. The electric motor in the linear actuator rotates a lead screw that moves the window up and down.

2. Medical equipment: Linear actuators are used in medical equipment such as hospital beds, operating tables, and dental chairs to adjust the height, angle, and position of the equipment. These actuators are often electric or hydraulic and provide precise control over the equipment's movement.

3. Robotics: Linear actuators are used in robots to control the movement of various components, such as robotic arms and grippers. They are used to provide linear motion in a variety of applications, such as assembly, material handling, and packaging.

4. Solar tracking systems: Linear actuators are used in solar tracking systems to adjust the angle of solar panels to follow the sun's movement. These actuators are often electric and provide precise control over the panels' movement to optimize energy output.

5. Aerospace applications: Linear actuators are used in aircraft and spacecraft to control the movement of flaps, landing gear, and other components. These actuators are often electric or hydraulic and must be reliable and durable to withstand the harsh conditions of space and high altitudes.
