1. A 28.4kg beam is attached to a wall with a hinge and its far end is supported by a cable. The angle between the beam and the cable is 90o. If the beam is inclined at an angle of theta=32.4owith respect to horizontal, what is the horizontal component of the force exerted by the hinge on the beam?
______
2. What is the magnitude of the force that the beam exerts on the hinge?
_____

How to discuss the results in relation to the objectives of the experiment of CENTRIPETAL FORCE? Next, how am i supposed to elaborate the results that I obtained if my results are confirmed the centripetal force theory.
A pendulum of length 9.00 m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 3m. (That is, 3.0 m is no longer free to swing.) How long does this pendulum take for one o..
