Homework 1. Compute the maximum deflection of a 10" by 14" simply supported solid rectangular redwood (S4S) beam. The span length is 15 ft and the beam is subjected to a uniformly distributed load of 1000 lb/ft. The allowable deflection is 1/300 of the span length. Is the beam satisfactory? Redwood: E = 1300 ksi 10 × 14 (S4S): I = 1950 in.4 2. Compute the maximum deflection for the beam of problem 1 if the loading consists of one concentrated load of 5000 lb at midspan instead of the uniformly distributed load. The allowable deflection is 1/300 of the span length. Is the beam satisfactory?
