EXAMPLE:
Determine load and deflection of a 30" 20P-2100 cantilever beam with a concentrated load on the end.
Solution:
1. From the load table on the previous page, the maximum load for a 30" span is 2,224 lbs. and deflection for that load is 0.177".
2. Multiply by factors from the table above. Load = 2,224 lbs. x 0.12 = 267 lbs. Deflection = 0.177" x 3.20 = 0.566"
3.Thus, the 30" cantilever beam will support a maximum concentrated load of 267 lbs. on the end and that load will cause a 0.566" deflection.
