The car weighs 1660 lbs and drives up the hill at a constant speed. Assuming the static friction coefficient between the wheels and the road is μ s = 0.76, determine the steepest angle θ that the car can climb without slipping if it is...

Parkway is the answer

Answerboth technicians (a) and (b);

If the heat engine is a perfect carnot cycle engine, thenefficiency = (t2-t1)/t2   where t1=temperature of cold reservoir ( ° k) = 135            t2=temperature of hot reservoir ( ° k)   = 325thereforeefficiency = (t2-t1)/t2 = (325-135)/325 = 0.5846 = 58%  note: this is the theoretical maximum efficiency of a perfect heat engine.   real-life engines do not achieve this value.
