Sawbuck smaller pieces ( in length) of firewood in rapid succession. A sawbuck should be heavy enough to negate any kickback from the saw while cutting. Building a sawbuck that is too light could result in injury as it may tip over while cutting, especially with a chainsaw. In Canada and Britain, and the United States, a sawbuck is called a "sawhorse", although this term also refers to a similar device used (often in pairs) to support wood planks. "Sawbuck" is also a slang term for a U.S. $10 bill, derived from the similarity between the shape of a sawbuck device
A value molecule. This leads to a problem when there are possible stabilizing electronic factors in a different system. The carboxylic acid substituent shown below is axial in the ground state, despite a positive A-Value. From this observation, it is clear that there are other possible electronic interactions that stabilize the axial conformation. It is important to note that A-values do not predict the physical size of a molecule, only the steric effect. For example, the tert-butyl group (A-value=4.9) has a larger A-value than the trimethylsilyl group (A-value=2.5), yet the tert-butyl group actually occupies less space. This difference can be attributed to
