HW3 Hints

3.1
Max bending stress is 36.2ksi.
Max torsional shear is 7.2ksi.
At "b" there is only shear, = 7.55ksi.


Shear modulus = 3.8Msi
Twist is 4.37°.
Total deflection is 1.22inches.

3.2


Deflection at tip from the Force at P is -3.339mm.
Deflection at P from the Moment at the tip is 7.246mm.
Total deflection at P is -0.73mm (downward).
Deflection at P is zero when the Moment is 3200Nm.
