Vein bursting is a common condition. I would recommend that you discuss this with your doctor as it may be a a sign of an underlying disorder that requires treatment. First of all, everyone occasionally experiences veins bursting. This results in an ecchymosis, or a bruise.
Couplings & Flexible Shafts. Couplings are devices used to connect two shafts together and are divided into two categories: Rigid and Flexible. Both are used for the purpose of transmitting power, rigid couplings being more limited in applications as compared to flexible couplings.
Torque converter elements. A fluid coupling is a two element drive that is incapable of multiplying torque, while a torque converter has at least one extra elementâthe statorâwhich alters the drive's characteristics during periods of high slippage, producing an increase in output torque.
