Problem 5.6-12 A cantilever beam of circular cross section and length supports a load acting at the free end (see figure). The beam is made of steel with an allowable bending stress of . Determine the required diameter of the beam, considering the effect of the beam’s own weight. d min 60 MPa P ± 400 N L ± 450 mm AB Problem 5.6-11 A two-axle carriage that is part of an overhead traveling crane in a testing laboratory moves slowly across a simple beam AB (see figure). The load transmitted to the beam from the front axle is 2200 lb and from the rear axle is 3800 lb. The weight of the beam itself may be disregarded. (a) Determine the minimum required section modulus S for the beam if the allowable bending stress is 17.0 ksi, the length of the beam is 18 ft, and the wheelbase of the carriage is 5 ft. (b) Select the most economical I-beam ( S shape) from Table E-2(a), Appendix E. 420 CHAPTER 5 Stresses in Beams (Basic Topics) Solution 5.6-11 N UMERICAL DATA (a) F IND REACTION THEN AN EXPRESSION FOR MOMENT UNDER LARGER LOAD
