    calulating the power that can be safely transfered by ashaft?

    Hi.

    This is the question i have been given on my progress check. Calualte the power that can be safely transferred by a 100mm shaft rotating at 150 revoulutions per minute?

    I have been trying to find a forumla for this but i have hit dead ends. Can any one shed any light on the matter

    Thanks alot

    Im not sure if this would help.

    P=Fv
    where P=power
    F=Force
    v=velocity.

    F=w^2r
    r= radius of the shaft ie (100*10^-3)/2
    w=2pi*f
    w=v/r to find v
    where f is the frequency ie 150 rev/mins
    convert that to rev/s

    can you finish?

    Thanks for replying if power = time x work how am i meant to get the power using the 100mm measurement and the revolutions? i may just be acting stupid?

    not time x work ... it's the product of torque and angular velocity.
