a torque angle gauge is used to measure _.
select one:
o a. the amount of additional twist applied to a bolt during the torquing procedure
o b. the angle of the driveshaft relative to horizontal
o c. the open and closed pressure of the valve springs
o d. the preload applied to a torsion bar

Explanation:

A torque - angle gauge is a tool used in mechanical work. When torquing a bolt, after reaching a certain initial torque, an additional twist (measured in degrees) is often applied. This additional twist is what a torque - angle gauge measures.

• Option b: Measuring the angle of a driveshaft relative to horizontal is not the function of a torque - angle gauge. There are other tools like protractors (in some cases) for measuring such angles in a more general sense related to orientation.
• Option c: Measuring the open and closed pressure of valve springs is typically done with spring testers that measure force (pressure in a force - related context for springs) rather than an angle - based gauge like a torque - angle gauge.
• Option d: Measuring preload on a torsion bar is usually about measuring force or deflection (in a linear or rotational sense related to force - displacement) rather than the additional twist (angle) during a torquing - like procedure.

Answer:

A. the amount of additional twist applied to a bolt during the torquing procedure
