STEM Lessons for College Students

10.88 .. DATA The V6 engine in a 2014 Chevrolet Silverado 1500 pickup truck is reported to produce a maximum power of 285 hp at 5300 rpm and a maximum torque of 305 ft # lb at 3900 rpm. (a) Calculate the torque in both ft # lb and N # m at 5300 rpm. Is your answer in ft # lb smaller than the specified maximum value? (b) Calculate the power in both horsepower and watts at 3900 rpm. Is your answer in hp smaller than the specified maximum value? (c) The relationship between power in hp and torque in ft # lb at a particular angular velocity in rpm is often written as hp = 3torque 1in ft # lb2 * rpm4>c where c is a constant. What is the numerical value of c? (d) The engine of a 2012 Chevrolet Camaro ZL1 is reported to produce 580 hp at 6000 rpm. What is the torque (in ft # lb) at 6000 rpm?

I have not created a lesson for this question yet.

Please leave a comment below with specifics about the question, and I will make a detailed lesson on it as soon as possible. (I can usually have something up within a day.)

NEED IMMEDIATE HELP? Get the student solution manual here: University Physics Manual otherwise, I should be able to get a video lesson up within a day or so.
