Follow our step by step solution on how to calculate Compressive Stress in Tappet of Rocker Arm of Engine Valve?

FIRST Step Consider the formula

σ c = \frac{4 \cdot (P g + P + P s)}{π \cdot {d c}^{2}}

Next Step Substitute values of Variables

∴

σ c = \frac{4 \cdot (1680N + 115N + 8.88N)}{π \cdot {8mm}^{2}}

Next Step Substitute values of Constants

∴

σ c = \frac{4 \cdot (1680N + 115N + 8.88N)}{3.1416 \cdot {8mm}^{2}}

Next Step Convert Units

∴

σ c = \frac{4 \cdot (1680N + 115N + 8.88N)}{3.1416 \cdot {0.008m}^{2}}

Next Step Prepare to Evaluate

∴

σ c = \frac{4 \cdot (1680 + 115 + 8.88)}{3.1416 \cdot {0.008}^{2}}

Next Step Evaluate

∴

σ c = 35887052.343076Pa

Next Step Convert to Output's Unit

∴

σ c = 35.887052343076N/mm²

LAST Step Rounding Answer

∴

σ c = 35.8871N/mm²
