Bending Moment in Rocker Arm near Boss of Rocker Arm given Bending Stress Solution

STEP 0: Pre-Calculation Summary

Formula Used

Bending Moment in Rocker Arm = (37*Bending Stress in Rocker Arm*Thickness of Rocker Arm Web^3)/3
M_barm = (37*σ_b*b_web^3)/3
This formula uses 3 Variables

Variables Used

Bending Moment in Rocker Arm - (Measured in Newton Meter) - Bending Moment in Rocker Arm is the amount of bending moment in the rocker arm (changes radial movement into linear movement) of any assembly.
Bending Stress in Rocker Arm - (Measured in Pascal) - Bending Stress in Rocker Arm is the amount of bending stress generated in the plane of the rocker arm of any assembly and tends to bend the arm.
Thickness of Rocker Arm Web - (Measured in Meter) - Thickness of Rocker Arm Web is the measurement of how thick is the web of the rocker arm's cross section.

STEP 1: Convert Input(s) to Base Unit

Bending Stress in Rocker Arm: 13 Newton per Square Millimeter --> 13000000 Pascal (Check conversion here)
Thickness of Rocker Arm Web: 8.6 Millimeter --> 0.0086 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_barm = (37*σ_b*b_web^3)/3 --> (37*13000000*0.0086^3)/3

Evaluating ... ...

M_barm = 101.980978666667

STEP 3: Convert Result to Output's Unit

101.980978666667 Newton Meter -->101980.978666667 Newton Millimeter (Check conversion here)

FINAL ANSWER

101980.978666667 ≈ 101981 Newton Millimeter <-- Bending Moment in Rocker Arm

(Calculation completed in 00.004 seconds)

Crank Rocker Mechanism

Crank Rocker Mechanism is a four-bar linkage. In this linkage, the shortest link rotates fully while the other link pivoted to the fixed link oscillates. It is a Grashoff linkage for which the sum of the lengths of the shortest link and the largest link is less than the sum of the lengths of the other two links.
In the crank rocker mechanism, the link adjacent to the shortest link is fixed. The position of the other three links does not affect the nature of the mechanism.
