MAE 472, Spring 2010 Homework #6 Due 4/29/10 Problem 1 For the frame (beam) structure below, find the final equilibrium equation for the entire system, including the appropriate boundary conditions. You do not need to solve the final equations. Assume E = 10 7 psi, I yy = 3 in 4 , A = 0.75 in 2 , L =100 in, p o = 40 lb/in. Problem 2 Construct an ANSYS model of the helicopter rotor blade shown below.

Unformatted text preview: For this problem, use E = 10 x 10 6 psi and = 0.3. Use the loading and axes given above. Use the cross-section dimensions shown below. From the model, plot the Von-Mises stress field on the cross-section at (a) y = 200 in., (b) y = 100 in. and (c) y = 0. Based on the plots, what changes to the cross-section would you recommend?...
