Crank Radius given Stroke Length of Piston Solution

STEP 0: Pre-Calculation Summary

Formula Used

Crank Radius of Engine = Stroke Length/2
r_c = l_s/2
This formula uses 2 Variables

Variables Used

Crank Radius of Engine - (Measured in Meter) - Crank Radius of Engine is the length of the crank of an engine. It is the distance between crank center and crank pin, i.e. half stroke.
Stroke Length - (Measured in Meter) - Stroke length is the distance traveled by piston in cylinder from BDC to TDC or vice versa.

STEP 1: Convert Input(s) to Base Unit

Stroke Length: 275 Millimeter --> 0.275 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_c = l_s/2 --> 0.275/2

Evaluating ... ...

r_c = 0.1375

STEP 3: Convert Result to Output's Unit

0.1375 Meter -->137.5 Millimeter (Check conversion here)

FINAL ANSWER

137.5 Millimeter <-- Crank Radius of Engine

(Calculation completed in 00.004 seconds)

Bearing Pressure on Piston Pin Bush

Go Bearing Pressure of Piston Pin Bush = Force on Piston Pin Bearing/(Inner Diameter of Bush on Piston Pin*Length of Bush on Piston Pin)

Maximum Force Acting on Piston Pin Bearing given Allowable Bearing Pressure

Go Force on Piston Pin Bearing = Inner Diameter of Bush on Piston Pin*Length of Bush on Piston Pin*Bearing Pressure of Piston Pin Bush

Bearing Pressure on Crank Pin Bush

Go Bearing Pressure of Crank Pin Bush = Force on Crank Pin Bearing/(Inner Diameter of Bush on Crank Pin*Length of Bush on Crank Pin)

Maximum Force Acting on Crank Pin Bearing given Allowable Bearing Pressure

Go Force on Crank Pin Bearing = Inner Diameter of Bush on Crank Pin*Length of Bush on Crank Pin*Bearing Pressure of Crank Pin Bush

Maximum Force Acting on Piston Pin Bearing

Go Force on Piston Pin Bearing = pi*Inner Diameter of Engine Cylinder^2*Maximum Pressure in Engine Cylinder/4

Mass of Reciprocating Parts in Engine Cylinder

Go Mass of Reciprocating Parts in Engine Cylinder = Mass of Piston Assembly+Mass of Connecting Rod/3

Maximum Height of Connecting Rod at Small End

Go Height of Connecting Rod Section at Small End = 0.9*Height of Connecting Rod at Mid Section

Minimum Height of Connecting Rod at Small End

Go Height of Connecting Rod Section = 0.75*Height of Connecting Rod at Mid Section Small End

Minimum Height of Connecting Rod at Big End

Go Height of Connecting Rod Section at Big End = 1.1*Height of Connecting Rod at Mid Section

Angular Velocity of Crank given Engine Speed in RPM

Go Angular Velocity of Crank = 2*pi*Engine Speed in Rpm/60

Maximum Height of Connecting Rod at Big End

Go Height of Connecting Rod Section = 1.25*Height of Connecting Rod at Mid Section

Crank Radius given Stroke Length of Piston

Go Crank Radius of Engine = Stroke Length/2

Crank Radius given Stroke Length of Piston Formula

What is a crank?

A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft or a separate arm or disk attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod (conrod).
The term often refers to a human-powered crank that is used to manually turn an axle, as in a bicycle crankset or a brace and bit drill. In this case, a person's arm or leg serves as the connecting rod, applying reciprocating force to the crank. There is usually a bar perpendicular to the other end of the arm, often with a freely rotatable handle or pedal attached.
