Question

An automobile steering wheel is shown. The ideal mechanical advantage of this wheel and axle is .

If a driver must exert a force of 2 N to overcome an axle resistance of 16 N, the AMA of the steering wheel is and its efficiency is %.

Answer 1

@Ohana: a couple of suggestions here:
(1) please post the illustration in which the automobile steering wheel "is shown."
(2) Please finish your sentence, "The ideal mechanical advantage of this wheel and axle is .............. "
(3) Define "axle resistance."
(4) Do not use appreviations such as "AMA." I'm an engineer by training, but am not able to recognize what your "AMA" means. Spell out the whole name.
(5) Instead of typing "its efficiency is," type "What is the efficiency of the steering wheel?" or "Find the efficiency of the steering wheel."

This is the Math section, whereas your post is most likely from Physics. Consider posting your question in the Physics section.

Good luck.
