Question

There is an ideal pulley system having 3 pulleys that produces maximum mechanical advantage and efficiency. Draw the arrangement with proper labelling of all the forces. By this pulley system, if 1000 kg of mass is to be lifted, then calculate the effort required at the free end of the string.

Answer 1

Answer:

There is an ideal pulley system having 3 pulleys that produces maximum mechanical advantage and efficiency. Draw the arrangement with proper labelling of all the forces. By this pulley system, if 1000 kg of mass is to be lifted, then calculate the effort required at the free end of the string.

Answer 2

Explanation:

let the effort required at free end of the string be E,

The M.A. of pulley system having 3 pulleys = 3

=>load=1000 kg

=1000 kg x 10 N

= 10000 kgf.

》M.A.=Load/effort

3 = 10000/effort

Effort(E)=10000/3

=3333.4 kgf.

I'am not good at calculations so sorry if in case the answer is not correct...

Hope this was helpful to u...

Good Luck
