Angle between crank and line of dead centres Solution

STEP 0: Pre-Calculation Summary
Formula Used
Crank Angle = asin(Ratio of length of connecting rod to crank length*sin(Inclination of Connecting Rod with Line of Stroke))
θ = asin(n*sin(φ))
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
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 length - Ratio of length of connecting rod to crank length is denoted by the symbol n.
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.
STEP 1: Convert Input(s) to Base Unit
Ratio of length of connecting rod to crank length: 1.9 --> No Conversion Required
Inclination of Connecting Rod with Line of Stroke: 15.5 Degree --> 0.27052603405907 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
θ = asin(n*sin(φ)) --> asin(1.9*sin(0.27052603405907))
Evaluating ... ...
θ = 0.532574447003983
STEP 3: Convert Result to Output's Unit
0.532574447003983 Radian -->30.5142680898477 Degree (Check conversion here)
FINAL ANSWER
30.5142680898477 30.51427 Degree <-- Crank Angle
