Angle between connecting rod and line of dead centres Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inclination of Connecting Rod With Line of Stroke = asin(sin(Crank Angle)/Ratio of Length of Connecting Rod to Crank)
φ = asin(sin(θ)/n)
This formula uses 2 Functions, 3 Variables

Functions Used

sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)
asin - The inverse sine function, is a trigonometric function that takes a ratio of two sides of a right triangle and outputs the angle opposite the side with the given ratio., asin(Number)

Variables Used

Inclination of Connecting Rod With Line of Stroke - (Measured in Radian) - Inclination of Connecting Rod With Line of Stroke is the angle of inclination of the connecting rod with the line of stroke of the piston.
Crank Angle - (Measured in Radian) - Crank Angle refers to the position of an engine's crankshaft in relation to the piston as it travels inside of the cylinder wall.
Ratio of Length of Connecting Rod to Crank - Ratio of length of connecting rod to crank length is the length of connecting rod divided by the length of the crank.

STEP 1: Convert Input(s) to Base Unit

Crank Angle: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
Ratio of Length of Connecting Rod to Crank: 1.86 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

φ = asin(sin(θ)/n) --> asin(sin(0.5235987755982)/1.86)

Evaluating ... ...

φ = 0.272164823883905

STEP 3: Convert Result to Output's Unit

0.272164823883905 Radian -->15.593895740472 Degree (Check conversion here)

FINAL ANSWER

15.593895740472 ≈ 15.5939 Degree <-- Inclination of Connecting Rod With Line of Stroke

Forces on Connecting Rod

During each rotation of the crankshaft, the connecting rod is often subject to large and repetitive forces: shear forces due to the angle between the piston and the crankpin, compression forces as the piston moves downwards, and tensile forces as the piston move upwards. These forces are proportional to the engine speed (RPM) squared.
