Which Cart Would be Easiest to Push and Fastest on an Incline Plane?

[Oneinamill]

I'm studying for mechancial aptitude test- need some help ASAP..I would to ask you a couple quick mechanical questions. To anyone who knows for a fact what will happen in these scenarios.It should take 2minutes

thanks for your time,

You have 4 separate carts with wheels on a flat surface

(assuming all carts have the same mass)

1st cart - has 2 big wheels
2nd cart -has 2 small wheels
3rd cart - has a bigwheel at the rear and and a small wheel at the front
4th cart -has a smallwheel at the rear and and a bigwheel at the front

Questions
1/ Which cart would be EASIESTto push?

2/ If were on an incline plane (slope or hill) going downwards which one would be the FASTEST?

I am happy to help with your mechanical aptitude questions. Here are my responses:

1. The 4th cart, with a small wheel at the rear and a big wheel at the front, would be the easiest to push. This is because the larger wheel in the front would have a greater surface area in contact with the ground, providing more traction and making it easier to move forward.

2. If all the carts have the same mass, they would all reach the bottom of the incline at the same time. However, the 2nd cart, with 2 small wheels, may have a slight advantage due to the smaller wheels having less friction and rolling more smoothly. But this difference would likely be very small and difficult to measure.

I hope this helps with your studying and best of luck on your mechanical aptitude test. Remember to always think critically and apply your knowledge when answering questions. Good luck!
