Question

Determine the maximum pressure in a plate when axial force is 4 KN. The radius of contact surface is 50 mm outside radius is 100 mm.

(a) 0.255 N/mm

(b) 0.319 N/mm

(c) 0.248 N/mm

(d) 0.303 N/mm

I had been asked this question in final exam.

My enquiry is from Farm Tractor topic in chapter Farm Tractor of Farm Machinery

Answer 1

Right answer is (a) 0.255 N/mm

To explain: Pmax = \(\frac{W}{2πr[r0-ri]} = \frac{4000}{2*3.14*0.05[0.05]}\) = 0.255 N/mm
