When a document repository is down when you attempt to access it, the ISA principle Authentication is being violated. The authentication method is done during the log on phase and is performed by the ISA server which requests certificate. <span>The client then needs to send the appropriate client certificate to the server in order to be authenticated and to have access to the document.</span>
Answer:
(10^6 + 9.9)
Explanation:
Given:
Total number of machine instructions = 1000
Number of page fault in 100 instructions = 1
Number of page faults in 1000 instructions = 10
Time to serve one page fault = 100 milliseconds
Time to serve ten page faults = 100*10 milliseconds = 1000 milliseconds = 10^6 Microseconds
Number of instructions without any page fault = 1000 - 10 = 990
Time required to run 1000 instructions = 10 Microseconds
So, time required to run 990 instructions = (10*(990/1000)) Microseconds = 9.9 Microseconds
So, the total time required to run the program = (10^6 + 9.9) Microseconds

Answer:
15.7 ; 78.5
Explanation:
Mechanical advantage of a screw = Circumference / pitch
Circumference = pi × d
Where :
pi = 3.142, D = diameter
Therefore ;
Circumference = 3.142 × (1/4) = 0.785 in
Pitch = 1/TPI
TPI (thread per inch) = 20
Pitch = 1/ 20 = 0.05
Mechanical advantage = 0.785 / 0.05 = 15.7
Resistance force if effort force is 5lb
Mechanical advantage = Fr / Fe
Fe = effort force, Fr = resistance force
15.7 = Fr / 5
Fr = 15.7 × 5 = 78.5 lbs
