Question
This crate holding 40 bricks, each of mass 1.3kg, is placed on a hydraulic lifting beam as shown.
A. State the order of the lever used here
B. Calculate the effort required to lift the load.
C. Calculate the mechanical advantage for this system.
D. Calculate the velocity ratio for the system shown.
holding 40 bricks, each of mass 1.3kg, is placed on a hydraulic li shown. the order of the lever used here. late the effort required to lift the load. late the mechanical advantage for this system. late the velocity ratio for the system shown below.Explanation / Answer
This is a 3rd order lever used here Load-Effort-Fulcrum.
Let F=force by hydraulic arm in upward direction.
52g x 6 = F x 1 .....where (g = 9.81)
F = 3060.72 N
Mechanical Advantage = 52 x g / 3060.72 = 1/6
[[...mechanical advantage = ratio of force at load to that at effort]...]
Velocity Ratio = 1 / Mechanical Advantage = 6
