Friction resistance Solution

Follow our step by step solution on how to calculate Friction resistance?

FIRST Step Consider the formula
Ffriction=F0+(μ⋅A⋅p)
Next Step Substitute values of Variables
∴ Ffriction=190N+(0.3⋅82.5mm²⋅4.24MPa)
Next Step Convert Units
∴ Ffriction=190N+(0.3⋅8.3E-5m²⋅4.2E+6Pa)
Next Step Prepare to Evaluate
∴ Ffriction=190+(0.3⋅8.3E-5⋅4.2E+6)
LAST Step Evaluate
∴Ffriction=294.94N
