Frictional Effort Lost Solution

Follow our step by step solution on how to calculate Frictional Effort Lost?

FIRST Step Consider the formula

F e = P - \frac{W}{V i}

Next Step Substitute values of Variables

∴

F e = 200N - \frac{1000N}{6}

Next Step Prepare to Evaluate

∴

F e = 200 - \frac{1000}{6}

Next Step Evaluate

∴

F e = 33.3333333333333N

LAST Step Rounding Answer

∴

F e = 33.3333N

How to Evaluate Frictional Effort Lost?

Frictional Effort Lost evaluator uses Frictional Effort Lost = Effort-Load/Velocity Ratio to evaluate the Frictional Effort Lost, Frictional Effort Lost is the portion of the input effort that is wasted due to friction or other inefficiencies in the machine. It can be calculated by subtracting the useful work output from the total work input. Frictional Effort Lost is denoted by F_e symbol.

How to evaluate Frictional Effort Lost using this online evaluator? To use this online evaluator for Frictional Effort Lost, enter Effort (P), Load (W) & Velocity Ratio (V_i) and hit the calculate button.
