Q. A block of iron has the dimensions of 3.00 cm x 3.00 cm x 3.00 cm. It has a mass of 213 g. When placed in water, the block sinks. What volume of water did it displace?
Q. Three chains act on the bracket such that they create a resultant force having a magnitude of 490 . If two of the chains are subjected to known forces, determine the angle of the third chain measured clockwise from the positive axis, so that the magnitude of force in this chain is a minimum. All forces lie in the - plane. Hint: First find the resultant of the two known forces. Force acts in this direction.
