Mechanical Advantage and Efficiency in Wheel and Axle Systems

What force is applied to the axle?

• 300 Newtons

• 8 centimeters

• 550 Newtons

• 16 centimeters

What is the diameter of the wheel?

• 300 Newtons

• 16 centimeters

• 8 centimeters

• 550 Newtons

What equation is used to calculate percent efficiency?

• AMA + IMA * 100

• AMA / IMA * 100

• AMA - IMA * 100

• AMA * IMA / 100

Why is the AMA not equal to the IMA in this scenario?

• Due to inefficiencies in the system

• Because of physical laws

• Because AMA is always higher

• Due to rounding errors

What assumption is made about the ideal effort force (FE) in the calculation?

• It is considered zero

• It is considered infinite

• It is not considered

• It is considered equal to FR

What does AMA stand for?

• Actual Mechanical Application

• Assumed Mechanical Advantage

• Actual Mechanical Advantage

• Assumed Mechanical Application

How is AMA calculated in this scenario?

• FR / FE

• DE / DR

• FE / FR

• DR / DE

What is the IMA value calculated in the video?

• 1.83

• 91.5

• 1

• 2

What does IMA stand for?

• Ideal Mechanical Application

• Ideal Mechanical Advantage

• Imaginary Mechanical Advantage

• Imaginary Mechanical Application

What is the final percent efficiency calculated?

• 50%

• 183%

• 91.5%

• 1.83%
