A 300-N force P is applied at Point A of the bell crank shown. (a) Compute the moment of the force P about O by resolving it into horizontal and vertical components. (b) Using the result of part (a), determine the perpendicular distance from O to the line of action of P.
1. Mutual Exclusion Condition The resources involved are non-shareable. Explanation: At least one resource (thread) must be held in a non-shareable mode, that is, only one process at a time claims exclusive control of the resource. If another process requests that resource, the requesting process must be delayed until the resource has been released. 2. Hold and Wait Condition Requesting process hold already, resources while waiting for requested resources. Explanation: There must exist a process that is holding a resource already allocated to it while waiting for additional resource that are currently being held by other processes. 3. No-Preemptive Condition Resources already allocated to a process cannot be preempted. Explanation: Resources cannot be removed from the process
