What are the two types of torque measurements?

Torque measurements are primarily expressed in terms of two units: inch-pounds and foot-pounds. Inch-pounds measure the amount of torque applied when a one-pound force is exerted at a distance of one inch from the pivot point. Conversely, foot-pounds represent the torque produced when a one-pound force is applied at a distance of one foot from the pivot. These two units are commonly used in engineering and mechanical applications to quantify rotational force, making them fundamental in the context of torque measurement.

The other options do not pertain to torque measurements. Weight pounds and mass pounds relate to weight and mass, which are different physical concepts. Torque pounds and pressure pounds also represent unrelated measurements, as pressure is typically expressed in units like psi (pounds per square inch) and does not have a direct correlation to torque. Lastly, while Newton meters is another valid measurement for torque, the correct focus of the question centers on the common imperial units, which are inch-pounds and foot-pounds.
