HI
I HAVE BEEN GIVEN THE FOLLOWING DATA
SHAFT DIA:150 mm
WEIGHT TO BE TILTED 12000 KGS
CALCULATE RPM OF SHAFT AND TORQUE REQUIRED FOR THE MOTOR TO START
HOW DO I GO ABOUT IT.

    First choose the matrerial for the shaft , it is usually C-40 . Use a design data book for better choices. Then fix the length of the shaft. With the load given calculate the Mass Moment Of Inertia, you already have the diameter fixed.
    The Torque needed to turn the given load will be
    TORQUE = MASS MOMENT OF INERTIA x ANGULAR ACCELERATION
    And,
    POWER = TORQUE x ANGULAR VELOCITY

    This is actually a very straight forward typical Text Book question. So first try to open your book and find the design procedure, its surely there. You only have to take the pains to open your book

    Assume this shaft is rotating along with the given load. In that case above formulae is correct. But for calculating angular velocity,you should know the RPM of shaft and for acceleration you need to know time for acceleration.
