Which of the following type of washers is used to hold the lock nut in place? Correct Answer Spring washer

Explanation:

Washers are of two main types:

  • Plain washers are inserted under screw heads or nuts to provide a suitable bearing area while tightening and to protect the component from damage.
  • Lock washers are used to prevent loosening due to vibrations, movements, or temperature variations. Common types include:
    • Spring washer
    • Snakeproof washer
    • Crinkle washer
    • Tab washer

Tab washer

  • These are thin metal washers designed with two or more tabs which project from the external diameter.
  • On assembly, a tab is bent against the component or sometimes into a hole in the component.
  • Other tabs are then bent up against the correctly tightened nut.
  • The deformation of the tab washer is such that it is intended to be used only once.
  • The following types of Tab washers are used.

Spring lock washer

  • As the nut tightens the washer against the piece below, one edge of the washer is caused to dig itself into that piece.
  • It results in increasing the resistance so that the nut will not loosen so easily which means it holds a nut at a place.

Consider a computer system with multiple shared resource types, with one instance per resource type. Each instance can be owned by only one process at a time. Owning and freeing of resources are done by holding a global lock (L). The following scheme is used to own a resource instance: function OWNRESOURCES(Resource R) Acquire lock L / / a global lock if R is available then Acquire R Release lock L else if R is owned by another process P then Terminate P, after releasing all resources owned by P Acquire R Restart P Release lock L end if end if end function Which of the following choice(s) about the above scheme is/are correct?
A multithreaded program P executes with x number of threads used y number of locks for ensuring mutual exclusion while operating on shared memory locations. All locks in the program are non-re-entrant. i.e. if a thread holds a lock l, then it cannot re-acquire lock l without releasing it. If a thread is unable to acquire a lock, it blocks until the lock becomes available. The minimum value of x and the minimum value of y together for which execution of p can result in a deadlock are:
