This assessment evaluates your understanding of gear ratios and torque calculations. You'll be assessed on mathematical skills, conceptual understanding, and practical applications, particularly in designing systems that maximize torque.
Question 1
1.
Calculate the torque produced when a force of 50 N is applied to a wheel with a radius of 0.2 m.
Question 2
2.
Question 3
3.
Question 4
4.
Describe how adjusting the gear ratio in your VEX robot affected its performance. Discuss any compromises between torque and speed.
Question 5
5.
What happens to the torque when the gear ratio is increased?
Torque increases, speed decreases
Torque decreases, speed decreases
Both torque and speed increase
Torque remains constant
Select the true statements about torque and speed trade-offs.
Increasing gear ratio can improve torque.
Higher torque always means higher speed.
Lower gear ratio increases speed but reduces torque.
Gear ratio doesn't affect speed or torque.
True or False: In a heavy machinery industry, maximizing torque is often more important than maximizing speed.
