Problem 1007 | Flexural stresses developed in the wood and steel fibers Jhun Vert Sun, 04/26/2020 - 12:50 am

Problem 1007
A uniformly distributed load of 300 lb/ft (including the weight of the beam) is simply supported on a 20-ft span. The cross section of the beam is described in Problem 1005. If n = 20, determine the maximum stresses produced in the wood and the steel.

Problem 833 | Reactions of Continuous Beams Jhun Vert Sat, 04/25/2020 - 12:35 pm

Problem 833
Refer to Problem 825 for which M2 = -980 lb·ft and M3 = -1082 lb·ft.



Problem 823 | Continuous Beam by Three-Moment Equation

Problem 823
A continuous beam simply supported over three 10-ft spans carries a concentrated load of 400 lb at the center of the first span, a concentrated load of 640 lb at the center of the third span and a uniformly distributed load of 80 lb/ft over the middle span. Solve for the moment over the supports and check your answers using the results obtained for Problems 819 and 822.
