Loss of Kinetic Energy during Perfectly Inelastic Collision

Go Loss of K.E During Perfectly Inelastic Collision = (Mass of Body A*Mass of Body B*(Initial Velocity of Body A Before the Collision-Initial Velocity of Body B Before the Collision)^2)/(2*(Mass of Body A+Mass of Body B))

Final Velocity of Bodies A and B after Inelastic Collision

Go Final Speed of A and B After Inelastic Collision = (Mass of Body A*Initial Velocity of Body A Before the Collision+Mass of Body B*Initial Velocity of Body B Before the Collision)/(Mass of Body A+Mass of Body B)

Coefficient of Restitution

Go Coefficient of Restitution = (Final Velocity of Body A After Elastic Collision-Final Velocity of Body B After Elastic Collision)/(Initial Velocity of Body B Before the Collision-Initial Velocity of Body A Before the Collision)

Equivalent Mass Moment of Inertia of Geared System with Shaft A and Shaft B

Go Equivalent Mass MOI of Geared System = Mass Moment of Inertia of Mass Attached to Shaft A+(Gear Ratio^2*Mass Moment of Inertia of Mass Attached to Shaft B)/Gear Efficiency

Kinetic Energy of System after Inelastic Collision

Go Kinetic Energy of System After Inelastic Collision = ((Mass of Body A+Mass of Body B)*Final Speed of A and B After Inelastic Collision^2)/2

Impulsive Force

Go Impulsive Force = (Mass*(Final Velocity-Initial Velocity))/Time Taken to Travel

Loss of Kinetic Energy during Imperfect Elastic Impact

Go Loss of Kinetic Energy During an Elastic Collision = Loss of K.E During Perfectly Inelastic Collision*(1-Coefficient of Restitution^2)

Speed of Guide Pulley

Go Speed of Guide Pulley = Speed of Drum Pulley*Diameter of Drum Pulley/Diameter of Guide Pulley

Centripetal Force or Centrifugal Force for given Angular Velocity and Radius of Curvature

Go Centripetal Force = Mass*Angular Velocity^2*Radius of Curvature

Total Kinetic Energy of Geared System

Go Kinetic Energy = (Equivalent Mass MOI of Geared System*Angular Acceleration of Shaft A^2)/2

Overall Efficiency from Shaft A to X

Go Overall Efficiency from Shaft A to X = Gear Efficiency^Total no. of Gear Pairs

Angular Acceleration of Shaft B given Gear Ratio and Angular Acceleration of Shaft A

Go Angular Acceleration of Shaft B = Gear Ratio*Angular Acceleration of Shaft A

Gear Ratio when Two Shafts A and B are Geared Together

Go Gear Ratio = Speed of Shaft B in RPM/Speed of Shaft A in RPM

Angular Velocity given Speed in RPM

Go Angular Velocity = (2*pi*Speed of Shaft A in RPM)/60

Efficiency of Machine

Go Gear Efficiency = Output Power/Input Power

Power Loss

Go Power Loss = Input Power-Output Power

Impulse

Go Impulse = Force*Time Taken to Travel

Speed of Guide Pulley Formula

Speed of Guide Pulley = Speed of Drum Pulley*Diameter of Drum Pulley/Diameter of Guide Pulley
N_P = N_D*d/d₁

Does a bigger pulley increase speed?

A smaller pulley turning larger pulley results in the larger one moving more slowly. If a smaller pulley turns into a larger one, the larger one will turn slower, but with more power available at the shaft. If a bigger pulley turns into a smaller one, the smaller one will turn much faster than the bigger one but with less power available at the shaft.
