Question

Capable of lifting a load three times the effort applied, with the effort distance being four times the load distance.

Express your answers in numerical form.
A) Mechanical Advantage (M.A)
B) Velocity Ratio (V.R)

Answer 1

The Mechanical Advantage (M.A) is 3, and the Velocity Ratio (V.R) is 4 for the described machine.

Step-by-step explanation:

The question involves calculating the Mechanical Advantage (M.A) and Velocity Ratio (V.R) of a simple machine that is capable of lifting a load that is three times the effort applied, with the effort distance being four times the load distance.

Mechanical Advantage (M.A)

Mechanical Advantage is the ratio of the load force to the effort force. Since the machine can lift a load three times the effort, the Mechanical Advantage (M.A) is 3:1 or simply 3.

Velocity Ratio (V.R)

Velocity Ratio is the ratio of the distance moved by the effort to the distance moved by the load. In this case, since the effort distance is four times the load distance, the Velocity Ratio (V.R) is 4:1 or simply 4.
