I really need help on this question because it is driving me insane.

A car weighs 8000 N. It has four wheels. Each tyre has a pressure of 20 N/CM2(cm squared).

If the weight is spread evenly, what is the weight supported by each tyre?

Please help me!

I think you might be overthinking this one a bit.

If the car weighs 8000 N and its weight is spread evenly over its four tires, each tire must be supporting 2000 N. The pressure of the tires was thrown in there just to confuse you!

The weight (messaured in kg)

2kiloNewton/g = 200kg
