AI Thread Summary
The discussion focuses on determining which of four carts with varying wheel sizes would be easiest to push and fastest on an incline. The carts include combinations of big and small wheels, with the first two having uniform wheel sizes. The consensus suggests that carts with larger wheels generally require less effort to push and perform better on inclines due to reduced rolling resistance. Additionally, a user inquires about the rarity of straight mountain roads, indicating a broader interest in mechanical principles. The thread also references a previous similar question and includes a request for aptitude test papers.

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?

Respected sir,
i am a Bsc Physics student. i have one doubt.why mountain roads are rare go to straight way
 
Hi

I found that a Jenny asked same question in this forum 1 month ago.

Please use search box at the top of site to find this question.

if anyone have daimler aptitude papers please send it to my mail id fazy_1989@yahoo.com... thank you!
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
