Question

Mechanical advantage is __ of two similar physical quantities.​

Answer 1

Answer:

Velocity Ratio

Explanation:

For a machine of a given desing ,due to friction and weight of the moving parts of machine , the velocity ratio does no change, but both machenical advantage and the efiiciency decreases.

Answer 2

Mechanical advantage is "Velocity Ratio" of two similar physical quantities.​

Explanation:

• For a machine of a given design, due to friction and weight of the moving parts of machine, the velocity ratio does not change, but both mechanical advantage and the efficiency decreases. thus the velocity ratio two similar physical quantities.
• Efficiency of machine has no unit, but are pure numbers. the mechanical(MA), of a machine is factor by which it multiplies any applied force. the MA may be calculated from the ratio of the force involved or ratio of a distances through which they move.
• In physical quantities is any physical property that can be quantified, that is, be measured using numbers.
