Angular Acceleration of Driven Shaft

Go Angular Acceleration of Driven Shaft = -Angular Velocity of Driven Shaft^2*cos(Angle between Driving and Driven Shafts)*sin(Angle between Driving and Driven Shafts)^2*sin(2*Angle Rotated by Driven Shaft)/((1-cos(Angle Rotated by Driven Shaft)^2*sin(Angle between Driving and Driven Shafts)^2)^2)

Velocity Ratio of Hooke's Joint

Go Velocity Ratio = cos(Angle between Driving and Driven Shafts)/(1-(cos(Angle Rotated by Driving Shaft))^2*(sin(Angle between Driving and Driven Shafts))^2)

Percentage Gradeability of Vehicle

Go Gradeability of Vehicle = (10200*Torque Generated*Overall Gear Reduction)/(Rolling Radius of Loaded Driving Tire*Gross Vehicle Weight)-Percentage Rolling Resistance

Axial Force of Multiplate Clutch using Uniform Wear Theory

Go Total Axial Load = pi*Pressure of Intensity*Inner Diameter of Friction Disc*(Outer Diameter of Friction Disc-Inner Diameter of Friction Disc)*0.5

Aerodynamic Resistance

Go Aerodynamic Resistance of Vehicle = 0.5*Density of Air*Frontal Area of Vehicle*Cruising Speed of Vehicle^2*Coefficient of Drag Exerted by Flow

Drawbar Pull

Go Drawbar Pull = (Torque Generated*Overall Gear Reduction*1000)/Rolling Radius of Loaded Driving Tire-Rolling Resistance at Wheel

Power Required to Propel Vehicle

Go Power required to Propel a Vehicle = (Total Resistance on Vehicle*Speed of Vehicle in Meter per Second)/Transmission Efficiency of Vehicle

Weight on Rear Axle

Go Weight on Rear Axle = (Total Weight being Distributed of Vehicle*CG Distance from Front Axle)/Wheelbase of Vehicle

Total Resistance on Vehicle

Go Total Resistance on Vehicle = Aerodynamic Resistance of Vehicle+Rolling Resistance at Wheel+Gradient Resistance

Effective Gear Ratio

Go Effective Gear Ratio = Old Tire Diameter/New Tire Diameter*Gear Ratio of Transmission

Weight on Front Axle

Go Weight on Front Axle = Total Weight being Distributed of Vehicle-Weight on Rear Axle

Engine Torque

Go Engine Torque = (9.55*Power required to Propel a Vehicle)/Engine Speed in rpm

Gear Step

Go Gear Step = Preceding Lower Gear Ratio Number/Gear Ratio Number

Final Drive Ratio

Go Final Drive Ratio = Rear Gear Ratio*Overdrive Ratio

Gear Step Formula

Gear Step = Preceding Lower Gear Ratio Number/Gear Ratio Number
φ = i_n-1/i_n

What is a gear step?

The relationship between the ratio of two neighboring gears is given by gear step. The transmission stepping should be large enough to enable the next lower gear (n-1) to be engaged when the maximum engine torque is reached in gear n. The smaller the gear step , the easier and more pleasant the gearshift action.

How to Calculate Gear Step?

Gear Step calculator uses Gear Step = Preceding Lower Gear Ratio Number/Gear Ratio Number to calculate the Gear Step, The Gear step formula is defined as the ratio of the preceding gear ratio to the considered gear ratio of the transmission system of vehicles. Gear Step is denoted by φ symbol.

How to calculate Gear Step using this online calculator? To use this online calculator for Gear Step, enter Preceding Lower Gear Ratio Number (i_n-1) & Gear Ratio Number (i_n) and hit the calculate button. Here is how the Gear Step calculation can be explained with given input values -> 1.34593 = 4.63/3.44.
