True or False: Thomas couplings are comprised of flexible, stacked stainless steel discs on both ends to provide flexibility and maintain driveshaft alignment.

• A. True
• B. False

Answer: (A)

Thomas couplings are indeed designed with flexible, stacked stainless steel discs at both ends. This construction allows for the necessary flexibility to accommodate misalignments between the driveshaft components while still ensuring a secure connection. The flexible nature of the discs helps to absorb shocks and vibrations that occur during operation, which can enhance the performance and longevity of the connected systems. Additionally, the stainless steel material provides durability and resistance to wear, further supporting the coupling's effectiveness in maintaining driveshaft alignment even under varying operational conditions. This design is essential for applications where precise alignment is critical to avoid potential mechanical failures and ensure smooth operation.
