1. Explain why it is easier to turn unscrew a hub cap on a tire with a tire iron with a longer handle. Does the longer handle increase/decrease the force needed to obtain the required torque to unscrew the hub cap?

Step 1
Torque is the rotational force applied to an object and is calculated as the product of the force applied and the distance from the pivot point (torque = force × lever arm length). Show more…

When unable to loosen the lug nut on an automobile tire, a mechanic may put a piece of pipe on the end of the handle of the tire iron so as to extend its length. How does that help? The mechanic can apply more force to the tire iron. The extra length means more torque for the same force The mechanic can apply the force more perpendicularly to the tire iron None of the above

Suppose you are trying to turn a stubborn bolt using a wrench. You exert a force F perpendicular to the end of the wrench with a length of 8" and the bolt does not move. Frustrated, you borrow your neighbor's wrench extender, which increases the length to 16". You then exert the same force F perpendicular to the end of the extended wrench and the bolt begins to rotate! Explain (in 2-3 sentences) why this adjustment worked using the concept of torque and its properties.

Pretend you have a friend that does not understand the concept of torque and explain this problem to him. Her truck gets a flat tire and to change it she must remove the lug nuts on the tire. You have 20 cm long wrench and a 30 cm long wrench. Which wrench should she use? Explain.
