Lifting Machines

Front

What does 'W' represent in lifting machines?

Back

W represents the load lifted.

Front

What does 'F' stand for in the context of lifting machines?

Back

F stands for the force applied.

Front

What is the formula for Mechanical Advantage (M.A.)?

Back

M.A. = Load / Effort = F / W

Front

How is Velocity Ratio (V.R.) calculated?

Back

V.R. = Load distance / Effort distance

Front

What is the formula for efficiency (η) in lifting machines?

Back

η = Efficiency = V.R. / M.A.

Front

In lifting blocks, how is the Velocity Ratio (V.R.) determined?

Back

V.R. is determined by the number of rope strands supporting the load block.
