A uniform stick of mass m and length l is suspended horizontally with end B at the edge of a table as shown in the diagram, and the other end A is originally held by hand.
The hand at A is suddenly released.
At the instant immediately after the release:
(a) What is the magnitude of the torque (τB) about the end B at the edge of the table?
Express your answer in terms of m, l and acceleration due to gravity g as needed (enter m for m, l for l and g for g).
τB=
(b) What is the magnitude of the angular acceleration α about the end B at the edge of the table?
Express your answer in terms of m, l and acceleration due to gravity g as needed (enter m for m, l for l and g for g).
α=
(c) What is the magnitude of the vertical acceleration a of the center of mass?
Express your answer in terms of m, l and acceleration due to gravity g as needed (enter m for m, l for l and g for g).

(d) What is the magnitude of the vertical component of the hinge force (N) at B ?
Express your answer in terms of m, l and acceleration due to gravity g as needed (enter m for m, l for l and g for g).
