# In the Fig Draw a Tackle to Lit a Load by Applying the Torce in a Convinient Direction. Mark the Position of Load and Effort. - Physics

Short Note

In the fig draw a tackle to lit a load by applying the torce in a convinient direction. Mark the position of load and effort.

(i) If the load is raised by 1 m, Through what distance will the effort move?

(ii) State how many strands of tackle are supporting the load?

(iii) What is the mechanical advantage of the sysytem?

#### Solution

correct winding of rope around pulleys, load and effort is as shown:

(i) Since there are five strings in the block and tackle system, therefore, the elocity ratio of the system is V.R = n 5

Now, V.R = "d"_"E"/"d"_"L"

or, "d"_"E" = 5 x "d"_"L" = 5 x 1 = 5m

(ii) 5 strands of tackle are supporting the load.

(iii) M . A = L/E

Here, L = 5T, E = T

M.A = (5"T")/"T" = 5
