The uniform beam AB in figure 12.39 has a mass of 900 ibm. g sub L is equal to 32.1740 ft/sec/sec.
a.) For a force F of 1200 ibf, construct a table listing the reactions at A and B if x varies from 0 to 32 ft in increments of 2 ft.
b,) Determine the value of F that makes the reaction at A 75% of the reaction at B when x=13 ft.
