Final answer:
The torque value for tightening the pivot bolt of an SCRT depends on the specific design and specifications of the machine.
Step-by-step explanation:
The subject of this question is Engineering.
Tightening the pivot bolt of an SCRT to a specific torque is a mechanical engineering concept. This is done to ensure that the bolt is securely fastened without being overtightened, which could lead to damage or failure.
As for the torque value, this would depend on the specific design and specifications of the SCRT. It is best to consult the manufacturer's documentation or engineering standards to determine the recommended torque value for the pivot bolt.
