Asked question is from Tractor Testing in chapter Farm Tractor of Farm Machinery

Answer 1

Right option is (b) 80°C

The explanation is: Brake test is done in cold condition as well as in hot condition. A brake is considered cold when its temperature is below 80°C. An artificial horizontal track is prepared, which gives good grip for tyres.
