Final answer:
The statement that shop air pressure is seldom higher than 50 psi is true. Air tools in industrial settings commonly operate around this pressure, while car tire pressures are generally between 32-35 psi.
Step-by-step explanation:
The statement that shop air pressure is seldom higher than 50 psi is True. In industrial and shop environments, air tools and equipment are typically designed to operate at pressures up to 50 psi. However, this number can vary depending on the specific application and the equipment being used. For example, tire pressures in cars are usually much less, recommended to be between 32-35 psi, which is corroborated by the fact that tire pressure is generally measured using a tire gauge that reads psi and is added to the atmospheric pressure (approximately 14.7 psi at sea level) to obtain the absolute pressure.
