Explanation:
The Mechanical Advantage (MA) is defined as the ratio between the force produced by the machine to the force applied to it.
=============================================================
So,
⇒
⇒ This means that the force produced is twice the applied force
Answer:
0 J
Explanation:
From the diagram below; we would notice that the Force (F) = Tension (T)
Also the angle θ adjacent to the perpendicular line = 90 °
The Workdone W = F. d
W = Fd cos θ
W = Fd cos 90°
W = Fd (0)
W = 0 J
Hence the force is perpendicular to the direction of displacement and the net work done in a circular motion in one complete revolution is = 0
