1. A 10 kg, 2 m long board is placed on two supports. One is at the left end the other is 1.5 m to the right of the first. You have two boxes. One with a mass of 2.0 kg, and one with a mass of 4.0 kg.
A. If the 2 kg box is 0.5 m from the left end and the 4 kg box is at the right end, what is the location of the center of gravity of the board and the boxes.
B. Sketch the arrangement in part A.
C. What are the forces on the board due to the two supports?
D. If you stack the 2 kg box on top of the 4 kg box will the board tip? Where is the new center of gravity?

A uniformly dense two by six board is 4.00 meters long and has a total mass of 10.0 kg. The board is supported at two locations, one support is 1.20 m from the left end, the second support is 1.60 m to the right of the first support. At the far right end of the board there is an additional 5.00 kg mass hanging from the board. a.) Sketch a free-body diagram for the board with appropriate labels. b.) Where...

a 5m diving board has a mass of 40 kg. it is secured by two supports as shown. Using the left edge as your reference point, construct a table showing the various forces, the lever arm, and their torques as measured around the left end (A). From your table, determine the force that each support must supply to hold up the board.
