Question

Quizplus · Accepted Answer

Drive shafts can be made from solid steel, but they can also be hollow or made from other materials like aluminum or carbon fiber for weight savings and efficiency. Additionally, a driveshaft typically requires at least two universal joints, one at each end, to accommodate the angular differences between the transmission and the differential.
