Identify the simple machine that is represented by a firefighter using an axe to split a door.

• Lever

• Inclined Plane

• Wedge

• Wheel and Axle

What simple machine is a axle with an inclined plane wrapped around it?

What is Mechanical Advantage (MA) in terms of force?

• The ratio of the magnitude of the resistance to the effort forces

• The ratio of the speed of the effort to the resistance force

• The ratio of the distance traveled by the resistance to the effort force

• The ratio of the function of the machine to the effort force

What does Mechanical Advantage (MA) allow designers to manipulate?

• Only the speed of a machine

• Only the distance and force

• Speed, distance, force, and function

• Only the function of a machine

Mechanical Advantage (MA) is also defined as the ratio of which of the following distances?

• Distance traveled by the effort and the speed of the resistance force

• Distance traveled by the effort and the resistance force

• Distance traveled by the function and the effort force

• Distance traveled by the speed and the resistance force

What does a mechanical advantage of 4:1 indicate about the effort force compared to the resistance force?

• The effort force magnitude is 4 times greater than the resistance force.

• The effort force magnitude is the same as the resistance force.

• The effort force magnitude is 4 times less than the resistance force.

• The effort force magnitude is 2 times less than the resistance force.

If a mechanism has a mechanical advantage of 4:1, how does the distance traveled by the effort force compare to the distance traveled by the resistance force?

• The effort force travels the same distance as the resistance force.

• The effort force travels 2 times greater distance than the resistance force.

• The effort force travels 4 times greater distance than the resistance force.

• The effort force travels 4 times less distance than the resistance force.

Which of the following statements is true regarding Mechanical Advantage (MA)?

• MA can be less than zero

• MA can be equal to zero

• MA can never be less than or equal to zero

• MA is always equal to one

What does IMA stand for in the context of mechanical systems?

• Internal Mechanical Assembly

• Ideal Mechanical Advantage

• Integrated Machine Application

• Inclined Mechanical Axis
