Answer 1

a) 22.2 N

Step-by-step explanation:

To find load effort. Identify load, efficiency and velocity ratio (VR)

Here given:

• Load = 100 N

• Efficiency = 75%

• VR (number of pulleys) = 6

Effort :

`\rightarrow \sf (MA)/(VR) = (Load \ / \ efficiency )/(VR) = (100 / 75 \% )/(6) = 22.22 \ N`
