Actuating Force Solution

Follow our step by step solution on how to calculate Actuating Force?

FIRST Step Consider the formula

F = P a \cdot A

Next Step Substitute values of Variables

∴

F = 2MPa \cdot 5500mm²

Next Step Convert Units

∴

F = 2E+6Pa \cdot 0.0055m²

Next Step Prepare to Evaluate

∴

F = 2E+6 \cdot 0.0055

LAST Step Evaluate

∴

F = 11000N
