The wall-mounted 2.9-kg light fixture has its mass center at g. determine the magnitudes of the reactions at a and b and also calculate the magnitude of the moment supported by the adjustment thumbscrew at c. (note that the lightweight frame abc has about 300 mm of horizontal tubing, directed into and out of the screen, at both a and b.) the connection at b is smooth.
