5 Questions
What is mechanical engineering the study of?
The study of physical machines that may involve force and movement.
How does a mechanism function?
A mechanism is a system of parts working together to make or prevent movement.
What components are necessary for a lever to function, and what are their roles?
A lever requires a fixed point called a fulcrum, an effort to move an object, and a load which is the object to be moved.
Describe a second-class lever and give an example.
A second-class lever has the load positioned between the fulcrum and the effort. An example is a wheelbarrow.
What does mechanical advantage refer to in the context of levers and mechanisms?
Mechanical advantage refers to the gain or additional force achieved by using a lever or mechanism.
Study Notes
Mechanical Engineering
- Study of physical machines that involve force and movement
Mechanism
- System of parts working together to make or prevent movement
Mechanical System
- Mechanisms and/or machines working together to get work done and produce movement
Types of Levers
- First-class Lever: Fulcrum is between load and effort
- Second-class Lever: Load is between fulcrum and effort
- Third-class Lever: Effort is between fulcrum and load
Mechanical Advantage
- Gain in effort achieved by using a lever or mechanism
