1. Which would NOT be a way of reducing friction?

• Making the surfaces smoother.

• Using lubricants such as waxes, oils, or grease.

• Changing from sliding friction to rolling friction using ball bearings.

• Using sand paper on snow and ice to help your car gain traction.

1. What can cause friction in a system?

• Rough surfaces, and surface roughness

• Lubrication
• Good alignment

• Smooth surfaces

1. What is the relationship between friction and temperature?

• As friction increases temperature increases.

• As temperature increases friction increases.

• As friction decreases temperature increases.

• As friction increases temperature decreases.

1. What is an automata?

• An automata is a type of plant
• An automata is a type of computer virus
• An automata is a mathematical model used to simulate the behavior of a system.
• An automata is a type of car

1. How does a motion graph relate to the shape of a cam? 

• The shape of a cam directly determines the motion of the follower, which is reflected in the motion graph.

• The motion graph is influenced by the weather conditions of the cam
• The motion graph is determined by the color of the cam
• The motion graph is unrelated to the shape of a cam

1. How can you reduce friction?

• Add an oil or lubricant.

• Increase the more surface area.

• Add sandpaper.

• Add more mechanical parts to the system.

1. How can you increase friction?

• Increase the surface area

• Add oil

• Add lubricants'

• Decrease the surface area

1. What is reverse engineering and how could it be used in the design process?

• Reverse engineering is the process of creating new products without analyzing existing ones.
• Reverse engineering is only used for copying existing products exactly as they are.
• Reverse engineering is the process of analyzing a product to understand its design and functionality. It can be used in the design process to gain insights into identify areas for improvement.

• Reverse engineering is not a valid method for gaining insights into product design.

1. Can an object have more than one type of motion?

• No
• Rarely
• Yes
• Sometimes

1. How could disassembling a mechanism help you to understand how the product functions?

• By observing how each part contributes to the whole, you can understand the purpose and operation of the product.
• By ignoring the individual components
• By painting each part a different color
• By using the mechanism without disassembling it
