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 one which has the substituent or substituents equatorial. When multiple substituents are taken into consideration, the conformation where the substituent with the largest A-value is equatorial is favored. The utility of A-values can be generalized for use outside of cyclohexane conformations. A-values can help predict the steric effect of a substituent. In general, the larger a substituent’s A-value, the larger the steric effect of that substituent. Methyl has an A-value of 1.74 while tert-butyl has an A-value of ~5. Because the A-value of tert-butyl is higher, tert-butyl has a larger steric effect than methyl. This difference in steric effects can
