Question
The 2.0kg object shown is hung on a wall with a nail that has been hammered through the black dot in the figure.
What is the gravitational torque acting on the object?
If the object has a moment of intertia 8.5
The 2.0kg object shown is hung on a wall with a nail that has been hammered through the black dot in the figure. What is the gravitational torque acting on the object? If the object has a moment of intertia 8.5A10^?2kg?m2 for rotation about the axis created by the nail, what will be the object's initial angular acceleration when released from rest? Express your answer using two significant figures. Use the usual convention that counter-clockwise rotation is positive.Explanation / Answer
gravationanal torque = Fg*r*cos25
torque = 2*9.8*0.17*cos25 = 3.02 Nm
Torque = I*alfa
alfa = 0.36*10^2 rad/s^2
alfa = 36 rad / s^2
