Question

Draw a diagram of a block and tackle system of pulleys having a velocity ratio 4. In your diagram indicate the points and direction of the load L and effort E. and also mark the tension T in each strand.

Answer 1

Answer:

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

Mechanical advantage (M.A.)=

$\frac{4t}{t}$

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

Explanation:

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.
