Problem 336 The cantilever beam shown in Fig. P-336 is built into a wall 2 ft thick so that it rests against points A and B. The beam is 12 ft long and weighs 100 lb per ft.
Solution 336
$2R_A = 10(2000) + 4[ \, 12(100) \, ]$
$R_A = 12\,400 \, \text{ lb}$ answer
$\Sigma M_A = 0$
$2R_B = 12(2000) + 6[ \, 12(100) \, ]$
$R_B = 15\,600 \, \text{ lb}$ answer
