Ramsay Test Mechanical Aptitude 2

Question 1

Two gears mesh together. If the driver gear has 10 teeth and the driven gear has 30 teeth, how does the driven gear turn compared to the driver?

Accepted Answer

Three times slower

Answer

A larger driven gear with more teeth turns proportionally slower, here three times slower than the smaller driver.

Question 2

When two gears mesh directly, how do their rotation directions compare?

Accepted Answer

They rotate in opposite directions

Answer

Directly meshed gears always rotate in opposite directions.

Question 3

A first-class lever is most clearly represented by which everyday tool?

Accepted Answer

A pair of scissors

Answer

Scissors are a first-class lever with the fulcrum (pivot) between the effort and the load.

Question 4

Moving the fulcrum closer to the load on a lever has what effect on the effort needed to lift it?

Accepted Answer

Decreases the effort needed

Answer

Placing the fulcrum nearer the load lengthens the effort arm, reducing the force required.

Question 5

In a fixed pulley system (single fixed pulley), what is the main advantage to the user?

Accepted Answer

It changes the direction of the applied force

Answer

A single fixed pulley only changes the direction of the force, not its magnitude.
