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

What does anti-malware software look for to determine that a program or a process is a virus?
Kryger [21]
Certain extensions of files. Sometimes, the name of the file could be something like Trojanx64.sys(I think). I had a few files of malware, but they were deleted. I believe the most common extension is .sys for viruses. Additionally, antivirus software could look into the properties of the program/process.
