Question

What is the pressure in the new uniform pressure theory?

(a) Pressure = w+π(r0^2-ri^2)

(b) Pressure = \(\frac{w}{π{r02-ri2}} \)

(c) Pressure = w*π(r0^2-ri^2)

(d) Pressure = w-π(r0^2-ri^2)

This question was posed to me in semester exam.

I want to ask this question from Farm Tractor topic in division Farm Tractor of Farm Machinery

Answer 1

The correct answer is (b) Pressure = \(\frac{w}{π{r02-ri2}} \)

For explanation: The uniform theory is applicable only when the friction lining is new. The pressure in the new uniform pressure theory is \(\frac{w}{π{r02-ri2}}. \)
