Assignment 2 stress analysis – bending circular beam, I beam in shear, … total mark 60
Problems 4.36[35], 4.44[25]
Q4.36 critical section AA of a crane hook is considered, for purpose of analysis, to be
trapezoidal with dimensions as shown. Determine the resultant stress (bending plus direct
tension) at point P and Q. (Use either Equation 4.9(Juvinall textbook P129) or Area Shape Factor
for the calculation of bending stress in the hook.) (Dimensions are in millimetre.)
4.44 For the 8-in. I-beam shown in figure below, compute the maximum transverse shear stress
(use equation 4.12) when the beam is simply supported at each end and subjected to a load of
1000lb in the center. Compare your answer with the approximation.
Equation 4.12
