Unformatted text preview: Exercises-Beams and Buckling (c) Donald E. Malen 1 Donald E. Malen 1999 25 mm 40 a) Find maximum stress and deflection at the load point for simply supported end conditions b) Find maximum stress and deflection at the load point for fixed end conditions c) For the simply supported case with requirements k 100N/mm P yield 2000N Determine the required thickness; consider only yielding behavior Which requirement dominates? (i.e. which requires the greater thickness) Seat mount Cross Member Number 3 Bar 1.5 m t=1.5 mm (for part a and b) P=800N at center Exercise 1.1 Donald E. Malen 1999 Engine 1m 40x80x1.5mm Motor Compartment Rail a) Determine the deflection of the tip of the beam and maximum direct stress and location for a 2000N load Load application at centroid Exercise 1.2a Exercises-Beams and Buckling (c) Donald E. Malen 2 Donald E. Malen 1999 Engine Engine 15 o Load application point moved to corner of section Section rotated 15 o . Load application point through centroid of section Motor Compartment Rail b) Determine the deflection of the tip of the beam and maximum direct stress and location for a 2000N load c) Determine the deflection of the tip of the beam and maximum direct stress and location for a 2000N load Exercise 1.2b,c Donald E. Malen 1999 Frame Cross Member 1.5 m Section Size: 40wide x 70high x 2 mm The rear powertrain mount is at the center of a cross member. The maximum vertical load is 1000N.The end condition for the cross member at the frame rails is simply supported. Calculate the deflection at the load point, and maximum direct stress and its location for: a) closed rectangular cross section with load applied at centroid b) rear facing C section with load applied at the web with warping unconstrained c) Same as b) but with warping constrained-use C w =h 2 b 3 t(2h+3b) where h height 12...
