Question

single fixed Pulley and movable Pulley both are separately used to lift a load of 50 KGF to the same height compare the efforts force applied​

Answer 1

Explanation:

Mechanical Advantage of single movable pulley=Load/Effort(E1)=2

50/Effort(E1) =2

Effort =25 kgf

and

Mechanical Advantage of single fixed pulley=

Load/Effort(E2)=1

50/Effort(E2)=1

Effort(E2) =50kgf

So, E2/E1=50/25

E2=2 E1

So, effort force of single fixed pulley is 2 times effort force of single movable pulley.
