Positive locking power transmission refers to a system where the connection between components is secure and prevents any slipping or movement during operation. This ensures that power is efficiently transferred without any loss. Force-locking power transmission, on the other hand, relies on friction or mechanical interlocking to transmit power, providing a strong and reliable connection. Positive locking refers to a mechanism that securely holds components together, while force-locking relies on external forces to maintain the connection. **

Positive locking power transmission refers to a system where the connection between two components is secure and does not allow for any slipping or movement. This is achieved through mechanisms such as gears or splines that ensure a precise and fixed transfer of power. On the other hand, frictional locking power transmission relies on the friction between two surfaces to transfer power. Positive locking refers to a mechanism that physically prevents movement or disengagement, while frictional locking relies on the resistance generated by friction to maintain the connection between components. **

Virus 71, also known as Enterovirus 71 (EV71), is a type of virus that belongs to the Enterovirus genus. It is a common cause of hand, foot, and mouth disease (HFMD) in children, particularly in the Asia-Pacific region. EV71 can cause mild symptoms such as fever, rash, and sores in the mouth, but in some cases, it can lead to more severe complications such as neurological issues and even death. Vaccines and good hygiene practices are important in preventing the spread of EV71. **
