OIT test questions and interview in 20 days

In a couple of weeks, I’ll be taking a test that consists of 40 general knowledge questions and 40 mechanical aptitude questions. The general knowledge sample questions sent by the hiring manager seem straightforward, but the mechanical aptitude ones are a bit more challenging. I’d appreciate it if someone could review these with me.

  1. Question 1: The wording is a little confusing, but I think that if the right-hand gear is turning clockwise, any gear attached to it on the right would turn counterclockwise. So, I believe the answer is A. Is that correct?

  2. Question 2: I think the answer is C—it seems straightforward. However, what would happen if the black pole were tilted at an angle to the right or left? How much does the angle affect the weight on the pole?

  3. Question 3: I’m guessing the answer is C, but I don’t really understand why. Could i please get an explanation on how to figure this out?

  4. Question 4: I’d guess the answer is A since if the cars are going the same speed through the curve, Car B would naturally be ahead.

If anyone has any resources or can suggest what to search up to study for the interview test please share it.
