reply and ask a question....

I chose question 7: Give an example in which a small force exerts a large torque. Give another example in which a large force exerts a small torque.

Seeing as how I work at a Toyota dealership and enjoy working on cars, this is a fitting question.

A small force can exert large torque when applied at a long distance from a pivot, such as a person using a long wrench to loosen a tight bolt. The wrench acts as a lever arm, with the bold as the pivot point. A small force applied at the end of the long wrench (far from the pivot) creates a large torque because the distance is large. This provides a strong turning effect ot overcome the bolt's resistance.

Conversely, a large force can exert a small torque if it is applied very close to the pivot, like pushing a door right next to its hinges. Even with a strong push (large force), the distance from the pivot point (the hinges) is very small. This results in a small torque, making it difficult to open the door efficiently because the lever arm is so short.

I look forward to your feedback, Professor and Classmates!
