Bending 1:

A solid steel bar has a square cross section of side b and is supported as shown. Knowing that for steel  r = 7860 kg/m³, determine the dimension b for which the maximum normal stress due to bending is (a)10 MPa, (b)50 MPa.

Bending 2:

A solid steel rod of diameter d is supported as shown. Knowing that for steel g = 490 lb/ft³, determine the smallest diameter d that can be used if the normal stress due to bending is not to exceed 4 ksi.

Bending 3:

Determine (a) the distance a for which the absolute value of the bending moment in the beam is as small as possible, (b) the corresponding maximum normal stress due to bending.

Bending 4:

Knowing that P = Q = 480 N, determine (a) the distance a for which the absolute value of the bending moment in the beam is as small as possible, (b) the corresponding maximum normal stress due to bending.

Bending 5:

Draw the shear and bending-moment diagrams for the beam and loading shown and determine the maximum normal stress due to bending.
