問題詳情
(2) A beam of rectangular cross section (width b and height h) supports a uniformlydistributed load of intensity q along its entire length L. The allowable stresses inbending and shear are σallow and τallow, respectively.
【題組】(2a) If the beam is simply supported, what is the span length Lo below which theshear stress governs the allowable load and above which the bending stressgoverns? (5分)
