When the kinematic pairs are coupled in such a way that the last link is joined to the first link to transmit definite motion and completely or successfully constrain motion, it is called a - Correct Answer Kinematic Chain

Explanation:

Kinematic chain:

  • A kinematic chain is a combination of kinematic pairs joined in such a way that each kinematic link forms two kinematic pairs having completely or successfully constrained motion between them.
  • A kinematic chain has no fixed link.
  • When all the links are connected in such a way that the first link is connected to the last link in order to get the close chain and if all the relative motion in this close chain are constraint then such a chain is called a parametric or kinematic chain.
  • A kinematic chain requires at least 4 link and 4 turning pair.

The relation between the number of link and number of kinematic pair is given by,

 l = 2p - 4

where, l = number of links, p = number of kinematic pair.

The above formula is used to check whether a given chain is a kinematic chain or not.

How does a host on an Ethernet LAN know when to transmit after a collision has occurred?
1. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.
2. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
3. You can improve the CSMA/CD network by adding more hubs.
4. After a collision, the station that detected the collision has first priority to resend the lost data.
5. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.
Consider the following statements: I. The degree of freedom for lower kinematic pairs is always equal to one. II. A ball and socket joint has three degrees of freedom and is a higher kinematic pair.

There is a hint in this question and a statement is given later. Carefully read the excerpts provided and determine the statement based on that episode. The current Australian team has lost three of their last five Test series. They lost their last two Test series, one of which was against Pakistan, which is not considered to be a strong team now. Australia's two best batsman, Steve Smith and David Warner are currently suspended and their absence has weakened the Australian team. There is a lot of dissatisfaction and introspection about how their national team plays in Australia, how they show aggression on the field, how they do not show respect to the team against them, and neglecting the media at the most, and focusing only on winning only, the discussion on the future of the game is ongoing. There are. Australian cricket never reached such a low level. This is the best opportunity to knock them into their own house. In other words, if this India could not beat Australia in Australia in this series, then it would prove that the campaign around this team is only the same: the propaganda. Legislation: The current Australian team won two of the last five Tests they played. Choose the right one from the next option A - The statement is completely true. B - Statement is most true. C - There is no definitive definition based on C-statement. D- Statement is completely false.
