Question

If the friction produces a torque of 5 Nm what maximum angular acceleration can the blade have if a technician pulls down on the blade with a 40.0 N force at a point that is 1m from the axle?

Problem 10.07 - Enhanced - with Solution
A certain type of propeller blade can be modeled as
a thin uniform bar 2.70 m long and of mass
26.0 kg. The blade rotates on an axle that is
perpendicular to it and through its center. However,
the axle does have friction.

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
