Hi everyone

I am trying to calculate the bending stress in gears inside an automotive transmission however my answers that I am getting don't seem to be right at all. I am trying to do this in metric.

Since I don't have any definitive data for an engine I am using max power at an RPM 164.1 kW at 8200 rpm 

What am I doing wrong because 1 .76 Mpa seems very small.

Have I got the method wrong?

Have I got the units wrong?
