Question

Draw a neat labelled diagram for the block and tackle system with velocity ratio equal to 2.

Answer 1

Answer:

(i) The labelled diagram of the system of block and tackle system of pulleys is shown indicating clearly the points of application and direction of load and effort.

(ii) Given : Velocity ratio (V.R.)=4, Load =4T, Effort =T

Mechanical advantage (M.A.)=

Effort

Load

=

T

4T

=4

Hence, the mechanical advantage of the given pulley system is 4.
