EXAMPLE.--If the weight of a carbon steel disc 7 in. diameter,
1-5/8 in. thick is desired, turn to page 233, where the per foot
weight of 7 in. round is given as 131.6 lb. Multiply this by the
decimal equivalent of 1-5/8 in., or 0.135, as shown in the above
table, and the product will be the net weight of the disc.

131.61 lb. = the weight of 1 ft. of 7 in. round.
0.135 = the per foot decimal equivalent of 1-5/8 in:
------------
65805
39483
13161
------------
17.76735 lb. = weight of disc 7 in. diam. 1-5/8 in. thick without any
allowance for finishing.
