Structural Engineering & Construction Situation 70 (PH)

PAST BOARD EXAM PROBLEMS Structural Engineering & Construction Situation 70 A wooden log is to be used as a foot bridge to span a 2m gap. The log is to support a concentrated load of 40 kN at midspan. Allowable shear stress = 1.2 MPa Allowable bending stress = 6.3 MPa 1. Calculate the diameter of the log needed for maximum shear. (240) 2. Calculate the diameter of the log needed so that the allowable bending stress is not exceeded. (320) 3. A 150mm wide rectangular log is to be used instead of the circular log. What is the required minimum depth of the log so as not to exceed the allowable bending stress? (300) Credits: 1. Intro Template:    • (FREE) 2D Square Intro (60 fps - No Text) ...   2.
