Question

How to find mechanical advantage and velocity ratio of this pulley system???


Pls i have icse board exam today

Helpp plss

Answer 1

Answer:

no of pulley = MA and velocity ratio is same

Explanation:

there are four strands to balance load and pulley and one strand for effort t using ma = load / effort we will get 4

Answer 2

This is a block and tackle Pulley system.

So, M. A = no.of pulleys in the system= V. R

Effort is always = T(1)

Load = no. Of pulleys

In this it L= 4T; E = T

M. A = 4 = V. R(ideal machine)

I am also going to write my physics board today!! (10th ICSE)

ALL THE BEST
