A pulley system with V.R. = 4 is used to lift a load of 175 kgf through a vertical height of 15 m. The effort required is 50 kgf in the downward direction. `(g=10Nkg^(-1))`
Calculate :
Distance moved by the effort.

Text Solution

AI Generated Solution

To solve the problem step by step, we will use the relationship between the velocity ratio (V.R.), the distance moved by the load (D_L), and the distance moved by the effort (D_E). ### Step 1: Understand the given values - Velocity Ratio (V.R.) = 4 - Distance moved by the load (D_L) = 15 m ### Step 2: Use the formula for Velocity Ratio The formula for Velocity Ratio is given by: ...
