Calculating power!

  1. May 24, 2014 #1
    1. The problem statement, all variables and given/known data

    The question provides three equations:

    Work = Torque x Angle (angle must be in radians).
    Power = Work/Time.
    As for linear measures, power can also be calculated as Power = Torque x Angular Velocity (where velocity is in rad/s).

    Using the data given, calculate the Power produced by the Quads at an angular velocity of 180 degrees/s. Give your answer to the nearest whole number (no decimal) and DO NOT include the units.

    Data: at 180 degres/s, quad torque = 118 Nm.

    2. Relevant equations

    Power = Torque x Angular Velocity
    P = T x w

    3. The attempt at a solution

    Power = Torque x Angular Velocity
    P = T x w
    P = 118 x 180 degrees/s.
    P = 21 240.

    To find radians, 21 240/57.3 = 370.68 P as radians/s.

    Does this sound correct? Please help! :)

    The correct units for power in SI are 1 Nm/s = 1 W

    Sorry of course it's Watts!

    Does the working out/answer look appropriate?
