Question

Front View A disk is rotating on a horizontal axis as shown in the figure. Answer the following questions if you pull down at A and push up at B along the axis of the disk. What is the direction of the torque acting on the disk? Incorrect right Incorrect up Incorrect down Incorrect in Incorrect left Correct: out Computer's answer now shown above. Incorrect. Tries 2/2 Previous Tries What is the direction of the initial angular momentum vector for the disk? up left , right- in- out - down Submit Answer Incorrect. Tries 1/2 Previous Tries The applied torque causes the wheel's axis (or angular momentum vector) to move. From the top view, what is the direction of motion of the L vector? Correct: clockwise (CW) Incorrect counter clockwise (CCW) Computer's answer now shown above. You are correct Your receipt no. is 163-2861 Previous Tries

Explanation / Answer

Torque using right hand rule will be acting in right.

Angular momentum will act in CW direction.

Left

Since the disk is speeding up, so the angular acceleration is in the same direction as the angular velocity else it would have slowed down.
